+For Dalgarno-McCray (DM) cooling, some of the initial parameters had to be changed.  The initial velocity used in the previous simulations would give rise to a post-shock temperature in the unstable region of the DM curve.  This led to the radiative instability, and thus unsteady shocks.  To avoid this, the initial velocity was lowered to 80 km/s.  Also, the cooling rate from the DM curve is much higher than that of the analytic form.  In order to see the cooling region, the grid had to be shrunk, resulting in a cell length of 10^13^ cm.
