Chtmultiregionfoam

Hello Foamers,

I am intending to simulate arc discharge in a laval nozzle, but using chtmultiregionfoam i always can't get a reseanable results , the time step always turns out to be extremly small and pressure and velocity distribution also unreasonable.

Can chtSolver really simulate transsonic and supersonic problems? I see from .C File that it'a combination of bouyantFoam and HeatconductionFoam.

Thanks in advance.

Hello,

chtMultiRegionFoam is not ideally suited for trans-sonic, supersonic cases. You will need to combine sonicFoam with the multiRegion capabilities of chtMultiRegionFoam.

Was anyone able to "merge" chtMultiRegionFoam with any solver for high speed flow? (rhoCentralFoam or sonicFoam).

Thanks.
