Hello,
I'm trying tu run the OpenFOAM case $FOAM_RUN/tutorials/compressible/rhoPimpleFoam/ras/angledDuct in Helyx-OS
However I always get the same error:

I would like to know how to set the Pre-Processing properly. Tanks!!
I set the conditions as follows:

Hi,

I get the same error, did you figure out what the problem was???
Is it due to the thermoPhysicalProperties or boundary conditions?
