Gas flow through pipe simulation help

Project link: link

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 conditionPressure inlet 2 pane, there is the symbol image. 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

Hi yapabox589 great that you reached out to us in the forum.

please be sure that your simulation only consist of one solid volume, in this case the flow region.

You can delete the part_1 (pipe) within the CAD Tool.

Also Set the outlet boundary condition to 0Pa. Without any pressure there will not be any flow.

Best regards Sebastian
