[FLASH-USERS] Are shockwaves standard in Flash

[Tomasz Plewa]

Seit -

Shocks are automatically included and resolved in at least basic hydro  
solver, PPM.

There is a module designed to detect multidimensional shocks:

FLASH2: shock_detect.F90
FLASH3: Hydro_detectShock.F90

This module was directly adopted from Woodward & Porter's sPPM code.

One dimensional shock detection is a part PPM (see Colella & Woodward  
paper; essentially look for pressure jumps of order of 0.3 associated  
with negative velocity divergence).

Hope this helps.
