Astronomical systems are usually much bigger in size, 99 larger in mass and more complex in structure than we can manipulate them on Earth to justify our models and their predictions. 100 Fortunately, computers and computational methods provide us easier and more convenient ways to study the astronomical systems. 101 Using numerical simulations, we can examine, correct, and improve our models until we understand our target system. 102 However, we must have the knowledge of using these methods and be aware of their pros and cons. 103 In this crash course, we aim to give our audience the first kick for properly using and understanding some of the 104 important numerical methods in astrophysics. 105 </p> 106 107 </div> 108 109 <div class="col-sm-3"> 110 111 <h3 class="section-title multiple-title">Topics</h3> 112 <div class="dropdown"> 113 <button class="dropbtn">Numerical hydrodynamics</button> 114 <div id="numhydro" class="dropdown-content"> 115 <a> Hydrodynamical equations </a> 116 <a> Discretization: particle vs grid </a> 117 <a> Finite differences for 1D hydro </a> 118 <a> Compare different methods </a> 119 <a> Stability analysis </a> 120 <a> Time step constraints </a> 121 <a> Multi-dimensional hydrodynamics </a> 122 <a> The wave structure of the equations </a> 123 <a> Example of 1D shock tube </a> 124 <a> More examples in 2D and 3D </a> 125 </div> 126 </div> 127 128 <br> 129 130 <div class="dropdown"> 131 <button class="dropbtn">N-body simulations</button> 132 <div id="nbody" class="dropdown-content"> 133 <a> Euler and Runge-Kutta methods </a> 134 <a> Symplectic integrators </a> 135 <a> Exact and approximate N-Body </a> 136 <a> N-Body Simulations with REBOUND </a> 137 </div> 138 </div> 139 140 <br> 141 142 <div class="dropdown"> 143 <button class="dropbtn">Self-gravity</button> 144 <div id="selfgravity" class="dropdown-content"> 145 <a> Gravity </a> 146 <a> Hydrodynamical equations with gravity </a> 147 <a> How to solve Poison equations </a> 148 <a> How to solve hydrodynamical equations with self-gravity </a> 149 </div> 150 </div> 151 152 <br> 153 154 <div class="dropdown"> 155 <button class="dropbtn">Numerical magnetohydrodynamics</button> 156 <div id="mhd" class="dropdown-content"> 157 <a> Theoretical aspects of magnetohydrodynamics </a> 158 <a> Recap of Hyperbolic, Parabolic and Elliptic equations, Conservative 159 and primitive variables in MHD, Numerical discretisation in MHD </

On the other hand, gravity, as the building block of astronomy, can govern the interaction between separate objects or affect the structure of a single object through self-gravity. On top of these, magnetic fields are usually present and complicate the behavior of the systems. Introducing some numerical methods for studying these four topics (hydrodynamics, N-body, self-gravity, and magnetohydrodynamics), will be the focus of the lectures in this crash course.</p> 172 <p>One lecture will be held per day from 27th to 30th of July, and the 31st of July will be the discussion day between the participants. In the first four days, there will be a lecture per day for 3-4 hours with a few breaks. The participants are supposed to work on the exercises for the rest of the day. Please note that, because of the different time-zones of our speakers, each day's schedule is different from the others. Please check the program for more details. On the last day, some volunteers among the participants will have the chance to present the results of the exercises and discuss them. 173 </p> 174 175 </div> 176 177 <div class="col-sm-12"> 178 179 <h3 class="section-title multiple-title">Prerequisites for the participants:</h3> 180 <p>Some basic knowledge of a <mark>programming language</mark> like C ( or Fortran), python, and a visualization software 181 (such as <a href="http://www.gnuplot.info/"><mark>Gnuplot</mark></a> or 182 <a href="https://github.com/gnudatalanguage/gdl"><mark>GDL</mark></a> for plotting the results is presumed. 183 Also, familiarity with the essential concepts of <a href="http://www.scholarpedia.org/article/Encyclopedia:Fluid_dynamics"><mark>hydrodynamics</mark></a> is assumed. 184 Participants are encouraged to use Gnu/Linux operating system and should have 185 <a href="https://github.com/astrofum/na2020"><mark>Pluto</mark></a> 186 and <a href="https://github.com/hannorein/rebound"><mark>Rebound</mark></a> codes installed on their computing systems before the workshop. 187 They should also have essential python libraries such as numpy, matplotlib, etc installed. 188 It is recommended to install a complete python distribution, e.g. 189 <a href="https://www.anaconda.com/"><mark>Anaconda</mark></a>, for more convenience. 190 191 To see step-by-step manuals for installing the codes, perform some simple tests and find materials (e.g. slides and movies) provided by lecturers, 192 please check the <a href="https://github.com/astrofum/na2020"><mark>workshop repository</mark></a>.</p> 193 194
