2D HD Riemann problems: isothermal cases

Introduction

These are 2D Riemann problems similar to Lax & Liu SIAM 1998, or also in Liska & Wendroff, SIAM J. Sci. Comput. 25, 3, pp. 995-1017, 2003 (section 4.4), but here modified to isothermal hydro setting. You can try to modify the setups, or compare different schemes.

How to run

Setting up the files

$AMRVAC_DIR/setup.pl -d=2

Compiling

Simply issue the make command:

make

Running the code

To run with e.g. 4 processors, use

mpirun -np 4 ./amrvac -i config4.par

Changing the parameters

A complete list of parameters can be found par.md.

Changing the physics and initial conditions

Have a look at the local file mod_usr.t. You can modify the initial conditions easily.
