Does nobody have an idea about this, why the mass flux is not conserved in this case or why the outlet suddenly has higher pressure than the inlet?

Did nobody encounter a similar problem?

Any...

sonicFoam - pressure driven pipe: flow continuity violation and waveTransmissive BC

Hello everyone,

I'm using OpenFOAM to analyse the gas flow (mass flow) behavior and arising pressure inside complex 3D structures with sonicFoam. My cases are somewhat similar to a nozzle, that...
