Dear Fabian,
thanks for the Reply. Unfortunately i am not that deep into the Topic so far… My Problem may rather sound trivial but it is the following:
I use pressure BC for the inlet in the poiseuille2d example and after the main Loop i just evaluate the mean velocity in order to calculate the Dary law, e.g. the permeability.
The Problem occurs now if i set FlowType=unForced, DESCRIPTOR = D2Q9Descriptor and apply the inlet pressure BC as hard Parameters
, ie. 100 Pa at the inlet and 10 Pa at the outlet.
Then the Simulation just breaks because with the given Parameters i get for all Parameters like uMax=inf, avEngergy=-nan, avRho=nan etc.
Any idea how to fix that simple example?
Best regards,
