Hello everybody,

i like to simulate a compressible flow through a channel. I suggest rhoCentralFoam is a good choice in my case, because its a laminar flow with a small velocity. I've started to modify the shocktube-case, but still get error messages if the internal pressure is smaller as the inlet- or outlet pressure.
I've experience in incompressible flow with icoFoam and wondering about the conversion to the compressible case.
1. How do I set the pressure at inlet, outlet and internal fields?
2. How do I set the velocity in this fields?
3. Is the heat-exchange only defined in the T - file?

Thanks a lot,
