What to simulate: Gas flow through a slice of a pipeline, therefore inlet, outlet and gauge pressure are equal.
Problem: I cannot generate the mesh and run the simulation. There is no log, just the announcement
A setup with 2 regions is being used in a single-region analysis type. Please make sure that all regions except for one have an Advanced Concept assigned to them.
In the Boundary condition → Pressure inlet 2 pane, there is the symbol 
. I edited the table inside it but got no clue what are they. The same with Pressure outlet 3. I intented face38@FlowRegion to be the inlet, face35 to be outlet.
As I am quite new to this, it is likely that I failed to report some details. Please feel free to ask.
Thank you
