1045					<p>From Autumn 2026 to Spring 2027 , CFD Direct is running its OpenFOAM Training courses — Essential CFD, Applied CFD, Productive CFD and Programming CFD — fully updated with the latest features of  the new version 14 release of OpenFOAM. The training uses new features in OpenFOAM v14 for more productive and effective CFD, including: field functions, units and the foamUnits utility, coded file input with the extended and improved set of directives, and modular Lagrangian.  We deliver the courses in Cologne, Germany and Chicago and Houston, USA, rather than online, because in-person training is more engaging,  improves understanding and confidence, and allows participants to share experiences with one another.</p>

1066					<p>OpenFOAM v14, produced by CFD Direct and released via The OpenFOAM Foundation, is the best version of OpenFOAM today.  By “best” we mean the software which best meets the critical needs of users — availability, usability, robustness and extensibility.  It is redesign work that has greatest impact on these criteria and which CFD Direct has provided time and again, delivering new, improved software components.  Examples include modular solvers, NCC, modular Lagrangian, units, field functions, coded file input, bounded MULES, dynamic zones, improved dynamic meshes, snappyHexMeshConfig, fvModels and fvConstraints.</p>

1086				<div class="entry-content clearfix">
1087					<p>In 2026, CFD Direct made units a standard feature of Foundation OpenFOAM.  The feature allows users to accompany numerical parameters in input files with units, e.g. [ft/s] for feet per second.  When the data is read with units, the numerical value is converted into the base unit, i.e.metres per second [m/s]  for the default SI unit set.  The new foamUnits utility makes units easy to use.  Units provide both the flexibility to specify parameters in the units given in the real world problem, but they can also make us aware of the associated dimensions and ensure values we provide are dimensionally consistent.  This gives the user greater certainty over correct specification of parameters.</p>

1108					<p>CFD Direct have added field functions to OpenFOAM, which provide a flexible, convenient way to initialise non-uniform fields in OpenFOAM.  The field functions are: <em>zonal</em>, corresponding to different zones; <em>surfaces</em>, corresponding to regions separated by surfaces; <em>distanceFunction</em>, calculated using a function of distance across the domain; and, <em>coded</em>, calculated using a coded function. Field functions are accompanied by the <em>functionalFixedValue</em> boundary condition (BC) for non-uniform values on boundary patches.  The functionality removes the need for a separate pre-processing step to intialise fields and some specialised BCs.</p>

1171					<p>In June 2025, Henry Weller at CFD Direct completed a rewrite of mesh zones and associated tools, released in OpenFOAM v13 by The OpenFOAM Foundation.  The aim behind the rewrite of mesh zones was to make them dynamic, so they would work effectively for complex CFD problems, especially involving moving meshes.  The new design includes createZones which provides a simpler, more powerful replacement for the lousy topoSet.   Other utilities which have been rewritten, and are far better to use as a result, include setFields, refineMesh (making the separate refineHexMesh redundant), createPatch and subsetMesh.</p>

1234					<p>This article is a user guide to the new Modular Lagrangian functionality in OpenFOAM.  This is a new implementation of Lagrangian functionality where data is stored as fields rather than in the objects representing particles or parcels (particle-based Lagrangian).  It will ultimately replace the original particle-based Lagrangian and is 75% complete and available in OpenFOAM-dev, with the first release in OpenFOAM v13.  Modular Lagrangian is far more extensible, since fields can be simply added, more efficient due to fewer function calls using field algebra and offers greater code reuse due to consistency with the rest of OpenFOAM.</p>

1318					<p>OpenFOAM provides leading CFD software to thousands of people within academia and industry for free.  However, CFD is inherently complex and competency in CFD requires more than simply “learning the software package”.  Our 3 OpenFOAM Training courses build CFD competency through a process of solution design with course prices equivalent to 1-2 weeks of payroll cost of a CFD engineer or 2% of a single core, commercial CFD licence.  Our schedule during Covid-19 travel restrictions includes scheduled live virtual training courses at times to fit with Europe and Americas time zones.</p>

1339					<p>Anyone investing in OpenFOAM Training must want training that delivers the best return on their investment.  It can be difficult to choose the best OpenFOAM training from the variety of disparate training offerings in a market that is particularly open due to the open source nature of the software.  Questions should be asked of potential training providers to establish their credibility and experience in OpenFOAM and in CFD training.  In this article we present 10 questions that might usefully be asked and present CFD Direct&#8217;s answers to the questions.</p>

1360					<p>In Year 9 of CFD Direct, we built on the success modular solvers and non-conformal coupling in OpenFOAM.  We replaced liquid film functionality and improved dynamic mesh, including mesh-to-mesh mapping, decomposition and redistribution, to the point that OpenFOAM can simulate internal combustion engines including piston and value motion. We managed the OpenFOAM Foundation, releasing OpenFOAM v11, packaging OpenFOAM-dev and publishing websites and documentation. We provided training and cloud services to OpenFOAM users, and began creating a new course &#8220;Productive CFD.&#8221;</p>

1444					<p>In 2016 we published a guide of Useful Tools in OpenFOAM with tools we first released in OpenFOAM v4. The tools included the post-processing CLI and template cases, and applications such as foamDictionary. We extended the article following the release of new tools such as TAB completion in OpenFOAM v5 and again later with the introduction of new tools in subsequent versions of OpenFOAM. This article describe more significant new tools introduced in OpenFOAM version 11, notably foamToC and foamPostProcess, to provide compatibility with its modular solvers, while maintaining backward-compatibility with application solvers.</p>

1465					<p>The OpenFOAM User Guide provides an introduction to OpenFOAM, through some basic tutorials, and some details about the general operation of OpenFOAM. OpenFOAM is a collection of approximately 250 applications built upon a collection of over 100 software libraries (modules). Each application performs a specific task, e.g the snappyHexMesh application can generate meshes for complex geometry, such as a vehicle. The simpleFoam application could then be used to simulate steady-state, turbulent, incompressible flow around the vehicle&#8230;</p>

1486					<p>CFD Direct have completely replaced the liquid film functionality in OpenFOAM. The new film functionality conserves mass, unlike its predecessor which was non-conservative and consequently inaccurate and unreliable for many problems.  It is implemented with the solver module framework, which enables coupling to other regions with gas flows, multiphase flows, particle clouds, solids etc, including calculations of conjugate heat transfer (CHT). As such, it is consistent with the rest of OpenFOAM so can use all the existing sub-modelling, e.g. thermodynamics, transport, etc.  The new implementation contains 50% of the code lines of the original one, despite being more functional. It is therefore cheaper and easier to maintain, while being more extensible and robust.</p>

1528					<p>“Dynamic mesh” describes situations where the mesh in CFD changes, either topologically by adding or removing cells, or by capturing the motion of the solution domain. It also relates to changes in the distribution of cells during a parallel simulation. This article describes the redesign of dynamic mesh functionality, released in OpenFOAM v10 and the development version of OpenFOAM (OpenFOAM-dev). The redesign was motivated by the development of non-conformal coupling (NCC). It specifically overcame a limitation of the previous dynamic mesh functionality which permitted only a single form of mesh motion or topological change within a simulation.</p>

1549					<p>In August 2022, CFD Direct introduced modular solvers to the OpenFOAM development version. Modular solvers are written as classes, in contrast to the traditional application solvers which have been integral to OpenFOAM since icoFoam in 1993.  They are simpler to use, maintain and understand than application solvers. They are more flexible; in particular, modules for different fluids and solids can be coupled across multiple regions, e.g. for conjugate heat transfer (CHT) with multiphase flow.  Modular solvers are deployed using the foamRun or foamMultiRun applications, which contain a generic solution algorithm for single and multiple regions, respectively. Additional modules and applications replace existing tools for data processing and case configuration.</p>

1591					<p>OpenFOAM is the leading free, open source software for computational fluid dynamics (CFD), distributed by The OpenFOAM Foundation. In 2014, OpenFOAM had accumulated significant “technical debt” due to a drive for new functionality at the expense of maintenance. Facing an unsustainable level of technical debt, CFD Direct was founded to manage and develop OpenFOAM back to a sustainable position. Code repair has targeted niche functionality that receives less testing. Redesign of larger, critical components of OpenFOAM has eliminated clusters of issues. By 2022, CFD Direct has recovered most of the technical debt, making OpenFOAM significantly more robust, usable and extensible.</p>

1654					<p>In May 2022, CFD Direct released Non-Conformal Coupling (NCC) in OpenFOAM to connect regions of a domain with independent meshes for applications including rotating geometry. NCC is a robust replacement for the Arbitrary Mesh Interface (AMI) and associated ACMI and Repeat AMI functionalities. Unlike the AMI functionalities, NCC ensures conservation which is essential for accuracy but also for stability, in particular in numerical schemes designed to maintain boundedness, e.g. in multiphase flows. NCC naturally works for partially-overlapping geometries, as illustrated by the case of opening and closing of a three port ball value.</p>

1801					<p>In March 2021, CFD Direct replaced fvOptions with new fvModels and fvConstraints classes. fvModels provided a more complete framework for implementation of complex models which could be optionally selected during a simulation. New fvModels were implemented for heat transfer and sources, which are easier to configure than a general fvOption. Pressure limiting was implemented as an fvConstraint named limitPressure, consistent with limitVelocity and limitTemperature. With additional fvModels such as cloud and surfaceFilm, solvers such as reactingFoam replicate the functionality of several existing solvers which are deprecated.</p>

1927					<p>In 2020, CFD Direct were tasked to develop multicomponent diffusion modelling in OpenFOAM with funding from the Process Engineering Consortium. The Consortium need models, e.g. Maxwell-Stefan, that represent complex diffusion of species in fluid mixtures, affecting both specie concentration and energy. As part of the work, we created a new ThermophysicalTransportModels library with a new interfaces for: fluxes of heat, q() and divq();  and fluxes of mass, j() and divj(). As a consequence, heat transfer became consistent across applications, boundary conditions and data processing. This critical code redesign is typical of our strategy for sustainable development of OpenFOAM, supported by dedicated maintenance funding from OpenFOAM supporters. </p>

1990					<p>In July 2020, CFD Direct released a framework for surface interpolation in interface capturing for multiphase flows  in OpenFOAM. All interpolation schemes, used for flux calculation in advection, operate with the MULES-based solvers, e.g. interFoam. The framework is easy to use, extensible, and robust due to bounded, conservative numerics. The new framework comes with a new family of interpolation schemes based on piecewise-linear interface calculation (PLIC). The PLIC schemes provide a promising alternative to standard interface compression, performing better for meshes with regions of cell refinement. All schemes are conservative, bounded and robust and can run efficiently with large time steps. </p>

2074					<p>In November 2018, Amazon Web Services (AWS) announed Elastic Fabric Adapter, a network interface for HPC applications running on EC2.  We previewed the EFA technology, running benchmark CFD simulations with OpenFOAM, presented previously: (1) strong scaling – 97 m total cells, external aerodynamics around a car; (2) weak scaling – 100 k cells per core, flow over a weir.  At 1008 cores, EFA delivered linear scaling in the strong scaling test and ~70% scaling in the weak scaling test.  With linear strong scaling, EFA enables faster solutions for the same cost simply by running on more cores.  The combination of open source software, C5n instances and EFA provides impressive HPC, at a price accessible to all.</p>

2095					<p>CFD Direct From the Cloud™ (CFDDFC) is a Marketplace Product for AWS EC2, that provides a complete platform with OpenFOAM and supporting software running on Ubuntu Linux. It enables simple, fast creation of a cluster of instances to run CFD with OpenFOAM.  We tested Amazon EC2 C5n instances, launched in November 2018, on 2 cases of steady-state, external aerodynamics around a car and transient simulation of water flowing over a weir.  With meshes of 50-100 million cells, results showed 70%-90% scaling at 504 cores. The cost of the simulations was in the order of $100, compared to $100,000+ to purchase on-premises hardware and licences of proprietary software.</p>

2179					<p>OpenFOAM sustainability involves developing software that meets critical needs of users, through a balance of resources, technology, investment and institutional support.  The critical needs are availability, usability, robustness and extensibility.  The critical work required to meet those needs are publishing, repair and redesign.  Employers rarely allocate time to individuals to contribute critical work, so it is generally left to “career maintainers” at CFD Direct.  With limited funding, decisions about the critical work are made by those who fund and/or contribute the work, via The OpenFOAM Hub.</p>

2263					<p>CFD Direct announces the release of their new 1 day Cloud CFD course, the fourth course in their portfolio of OpenFOAM Training.  The course enables users to run CFD with OpenFOAM on AWS, training the tools and processes for inexpensive, secure, efficient cloud use.  The course addresses the main concerns of using public cloud: cost management, security, efficient CFD and data management.  It exploits the cost benefits of cloud: meeting fluctuating demand for hardware at a cost that represents consistent, high utilitisation; and using cheaper, spare capacity, with an application that does not require 100% availability.</p>

2347					<p>In May 2017, we implemented water wave modelling into the public, development line of OpenFOAM (OpenFOAM-dev), to simulate flow conditions experienced in marine and offshore engineering, e.g. on a ship in open water.   The initial implementation includes the  first order Airy wave and the second order Stokes wave (Stokes II), a second-order accurate utility to apply waves for case initialisation to the entire domain.  A verticalDamping source (fvOption) provides wave damping towards outlet regions and an interfaceHeight function object processes interface elevation at specified locations.</p>

2368					<p>In April 2017, we added barycentric tracking into the public, development line of OpenFOAM (OpenFOAM-dev), as a complete replacement to the tracking algorithm that existed in OpenFOAM for over 10 years.  Barycentric tracking works on any decomposed tet mesh, irrespective of mesh quality, including poor quality, flat and inverted tetrahedra.  The new development was funded from the €100 k for OpenFOAM maintenance, raised through the OpenFOAM Foundation in 2017, in which “particles and tracking” was identified as an area in OpenFOAM “requiring significant code refactoring and/or rewriting”.</p>

We produced the major new version 4.0 release of OpenFOAM and the minor update version 4.1 release.  We transformed OpenFOAM-dev into stable software of “always-releasable” quality and package it weekly for Ubuntu.  Ubuntu packs can now be installed directly on Windows 10 and we also provide “containerized” versions, hosted on Docker Hub, accompanied by launch scripts for easy installation of OpenFOAM on Linux and macOS.</p>

We upgraded the system and and analyzed metrics relating to timely resolution of issues which concluded that current unresolved issues relate to badly designed components of OpenFOAM that require significant code rewriting.  To fund that repair work and ongoing maintenance, we ran a successful campaign to raise €100 k from companies that benefit from OpenFOAM.  We carried out substantial maintenance to OpenFOAM websites, significant updates to documentation, and administration for the OpenFOAM Foundation.</p>

2473					<p>In Year 2, CFD Direct updated its OpenFOAM cloud computing platform — CFD Direct From the Cloud (CFDDFC) — to OpenFOAM 4.1, running on Ubuntu 16.04.  Feedback from users was very positive, including a 5-star rating on the CFDDFC Marketplace Product page at  at Amazon Web Services (AWS).    We became an Advanced Technology Partner of AWS, and produced a case study on the cost of CFD on AWS EC2 that concluded, in particular, that the cost of Spot instances was approximately 40% of the total cost of ownership of on-premises hardware.  We made CFDDFC available on AWS X1 instance types, running simulations on 32 and 64 physical cores in a single instance.</p>

2515					<p>Cloud computing replaces large upfront expenses with low, variable payments that only apply to what you use.  CFD simulations cover a range of sizes and complexity.  Activity is generally interrupted by quiet periods when simulations are halted, e.g. when a simulation ends non-working hours, during analysis of results or preparation of a new simulation, etc.   The fluctuating demand makes CFD well suited to a pay-per-use model.  Users need to understand the costs involved to get the best value from cloud and be confident that they fall within budget.  This article explains the costs, with an example of an external aerodynamics calculation with OpenFOAM using CFD Direct From the Cloud™ (CFDDFC) on Amazon Web Services (AWS).</p>

2536					<p>A breakdown of outstanding issues in OpenFOAM (2016-10-26) shows 90% of unresolved issues falling within only 7 categories.  The two worst offenders account for almost half of all unresolved issues: 1) AMI, ACMI and cyclic interfaces; and, 2) heat transfer, including conjugate heat transfer (CHT).  These categories, and “particles and tracking” and “sources/constraints” in particular, require significant refactoring and/or rewriting.  Their current state of disrepair was caused by poor funding under a roadmap development strategy.  Funding of agile development of OpenFOAM is now needed  to support our aim to improve quality, with a target 50% reduction in unresolved issues in 2017.</p>

2557					<p>Agile development of OpenFOAM emerged following the public distribution of the development line in December 2014.  It relies on user participation, which is encouraged by rewarding users for reporting issues with timely resolution.  OpenFOAM was in poor health at version 2.3.0, with unresolved issues increasing rapidly and long resolution times. Following the move to agile development, unresolved issues are reduced and under control, with ~70% of issues resolved in 1 day and ~90% resolved in 1 week, taking OpenFOAM to a new level of quality and maturity (always releasable) by version 4.0.</p>

2578					<p>The OpenFOAM Issue Tracking system exists to enable users to report issues.  An issue exists when OpenFOAM behaves in a manner that does not meet reasonable expectations, including in design and usability. OpenFOAM is mature, quality software, whose successful development demands that issues are resolved in a timely manner.  Roadmap development obstructs issue resolution, resulting in unreliable software and inefficient development.  Instead, free, open source software can exploit agile development with frequent code release, as the best strategy for CFD development.  Users should adopt continuous upgrade to minimize cost and to benefit the agile development strategy.</p>

It first assembles an equation for combined mechanical and thermal energy, i.e. total energy, in terms of material derivatives.  It then presents an equation for thermal, or internal, energy.  The total energy equation is then provided in terms of local (partial) derivatives, both in terms of internal energy and enthalpy.  The implementation of the energy equation in solvers in OpenFOAM is then described.</p>

2641					<p>This article provides information on tensor mathematics, relevant to fluid dynamics and computational fluid dynamics (CFD).   It describes scalars and vectors and typical algebraic vector operations.  It follows with second rank tensors, their algebraic operations, symmetry, skewness and tensor invariants such as trace and determinant, higher rank tensors, co-ordinate system and change of axis.  Tensor calculus is introduced (div, grad, curl and Laplacian), followed by integral theorems of Gauss and Stokes, with a physical representation of div and curl, and more.</p>

2704					<p>OpenFOAM version 4.0 is the latest major version of OpenFOAM, released on 28th June 2016. CFD Direct was by far the largest contributor to OpenFOAM 4.0, contributing the vast majority of new functionality including post-processing, numerous boundary conditions and physical models.  Additionally, we contributed across all other aspects of software engineering that make OpenFOAM a mature, modern environment for CFD.  This article provides the inside view of that work on the software engineering behind OpenFOAM 4.0, contributed largely during a 3 month period from April-July, 2016.</p>

We carried out maintenance on OpenFOAM, reducing the number of outstanding issues by approximately 35%, involving over 500 commits to the bug fix line of OpenFOAM 3.0.  We managed the OpenFOAM Foundation, established a free OpenFOAM documentation resource, and our posts on social media updated users about developments to OpenFOAM , which encouraged a strong community to support and contribute to OpenFOAM as free software.</p>

2872					<p>Where is the Source Code? is a campaign to promote free, public distribution of OpenFOAM and software that links intimately to OpenFOAM.   It is in response to a general dissatisfaction with the practice of making a modification to OpenFOAM, then promoting the benefits of the modification, without making that modification freely available to the public, often in order to sell it commercially.  The campaign is simply to get people to ask &#8220;Where is the Source Code?&#8221; when modifications like this are promoted, for example after a conference presentation or in a response to a discussion on the Internet.</p>

2914					<p>An earlier article described the OpenFOAM training through which Jenya Collings and I provided almost 500 days of instructor-led, classes to 2,500 particpants.  That training mainly described the workings of the OpenFOAM for the early adopters of the software, but we need training whose focus is to enable people to deliver successful CFD solutions.  CFD Direct have developed this training over several months, with a modular format that addresses all components of CFD and where the participant learns through experience on a wide range of real-world CFD examples.  The training is built on developments to OpenFOAM that make it easier to use, such as template cases, packaged tools, reorganised input and re-coded features.</p>

2935					<p>In 2008, the Directors of CFD Direct began the first significant OpenFOAM Training courses.  The training was written for early adopters of OpenFOAM at a time when OpenFOAM was far less functional than today.  The courses largely emphasised how OpenFOAM worked and a lot of time was devoted to code customisation.  We pioneered a convenient method of providing participants with a running version of OpenFOAM using a persistent live installation that booted Linux from an 8GB USB pendrive.   The wider user community benefited from our example cases, e.g. the motorbike case, and code changes made for the courses becoming part of OpenFOAM and our adoption of Ubuntu leading to the release of OpenFOAM packaged for Ubuntu.</p>

2956					<p>CFD analysis involves competency in fluid dynamics, physical modelling, meshing, numerical methods, data analysis, computing, programming.  It is difficult to obtain knowledge and experience in these CFD competencies, even with broad access to information brought by today&#8217;s Internet. People are forced to rely heavily on colleagues or online forums because most CFD teaching is generally inadequate.  At CFD Direct, it is our aim to support  people to deliver timely, quality CFD analysis at a reasonable cost.  Our belief in open source software means that the public are able to access information, such as numerical methods and physical models, through the source code of OpenFOAM.   We supplement this by providing support and training services, and through our contributions to OpenFOAM, including free technical information.</p>
