Tutorial problem: "rhopSonicFoam - shockTube" with high pressure
 
Hello!

For getting experience in high pressure simulation I try out the "shockTube" turotial of rhopSonicFoam.

When unchanged, the tutorial works fine.

But when I changethe pressure in "SetFieldsDict" to a higher value (100.000.000 instead of 10.000 Pa), simulation fails.

I cannot figure out what settings to change for the simulation of that high pressures. Is it because of the boundary conditions or is this more of a solver setup problem?

Is someone experienced in setting up a high pressure case?
