Hello all,<br>
<br>
I'm relatively new in using the FLASH code and am trying to set up a<br>
simulation comparable to the Laser Slab example.<br>
However, when changing the material properties, the different regions<br>
start to rarefy at their respective borders. This is probably due to the<br>
high pressure difference between the thin gas (vacuum) and the target<br>
region.<br>
<br>
Does anybody has experience on modifying the initial conditions such<br>
that the pressure is better matched. Alternatively, is it possible to<br>
toggle material mixing or general hydro processes with a temperature<br>
switch, i.e. defining a lower limit for which the material is kept at<br>
initial conditions?<br>
<br>
Thank you!<br>
<br>

The module in FLASH was contributed by Andrea Mignone, the author of Pluto.<br>
The module is FLASH is several years old, and it is very likely that Andrea<br>
has been updating the implementation in Pluto. That is why it would be<br>
better to use Pluto. Also, FLASH+Chombo has limited capability, many of<br>
FLASH modules do not interoperate with Chombo, whereas Pluto uses Chombo<br>
for AMR. So overall Pluto seems like a better option for you.<br>
