Hydrostatic halo in equilibrium in an isothermal potential. Running for 10 dynamical times. To make the initial conditions we distribute gas particles randomly in a cube with a side length twice that of the virial radius. The density profile of the gas is proportional to r^(-2) where r is the distance from the centre of the cube. The parameter v_rot (in makeIC.py and hydrostatic.yml) sets the circular velocity of the halo, and by extension, the viral radius, viral mass, and the internal energy of the gas such that hydrostatic equilibrium is achieved. To run this example, make such that the code is compiled with either the isothermal potential or softened isothermal potential set in src/const.h. In the latter case, a (small) value of epsilon needs to be set in hydrostatic.yml. ~1 kpc should work well. The plotting scripts produce a plot of the density, internal energy and radial velocity profile for each snapshot and divides the profile by the expected profile. The script test_energy_conservation.py shows the evolution of energy with time. These can be used to check if the example has run properly.
