[FLASH-USERS] Boundary condition problem

[Markus Haider]

I did some more investigation of this problem. If I run this code in a 
modified version of Flash 3.1.1 using the unsplit 3D staggered mesh 
solver the artifacts do not occur. If I however switch (leaving 
everything else unchanged) to the Split PPM solver the artifacts are 
present.

As stated, the artifacts are present only in temperature, energy and 
pressure.

Cheers,
Markus
