[FLASH-USERS] Altering Velocity Causes Anomalous Pressure

[James Guillochon]

Hi everyone,

I am altering the velocity of a couple of grid squares in my simulation 
in the Driver_sourceTerms function at each time step, and after a couple 
hundred steps I end up with a grid cell or two with a ridiculously high 
pressure/density, which causes the Helmholtz EOS routine to not 
converge. I was wondering if there are any other variables I should be 
altering when I give these grid cells their new velocities? Or if there 
is a better place in Flash to be adjusting the velocities than the 
Driver_sourceTerms routine?

Thanks!
