[FLASH-USERS] Expansion of Target

[Brian Kraus]

Hi Phani Sri and all,

This seems the same as an issue I had been seeing when I put a high-density
layer into the Laser Slab. I modified the region between 1 to 2 microns
into the target to have the density of Ti instead of Al, and when I evolve
the system I see artificial shocks develop from the boundaries between low
and high density solid. I am not sure if these shocks affect any dynamics
from the laser, but it would be nice to properly model a solid that does
not support these relaxation shocks.

Thank you for any advice on either Phani Sri's problem or this one.

Best,
Brian
