as of now, yes, no matter what I do I am experiencing crashes rather soon in the solution.
Thank you.

Your uploaded files are working.
I dont know what you are wanna do exaclty couse your files are in caos
And I think you are not using OF in a terminal arent you? Couse all headers are away.

Well i can solve that block with rhoSimplecFoam

and I am not sure if you declare BC in k and omega like that:

Code:
    inletXmin
{
    type            freestream;
    freestreamValue      uniform 12.500000;
    value           uniform 12.500000;
}
Never seen that!
But I have never used the freeStream BC.
I am confused, where is your problem?

Well maybe there is a problem of your BC for p and U

Tobi, that patch is not considered because of the internal flow condition which meshes inside the duct and thus eliminates the patches outside that domain.

okay I understand
But your case is working, so whats the problem? I just wanted to help you but I think you dont need my help at all.
Hope you get it work and have a nice sunday.

hi Tobi, I included the streamlines I got using the incompressible solver simpleFoam in order to showcase the geometry and desired flow. Unfortunately, to perform a realistic and accurate simulation at the inlet speeds I used - 100m/s, a compressible flow solver is required. and that's where it crashes.

hi,

okay you used a simpleFoam solver to test if its working. Hmmm ... but your continuity crashes too.
Look at your values. Maybe you can have a look at the first time step and see where your problem zones are.

Can you uplaod your case, if yes, I c an have a look at it.
