Hey there,
I am quite new to comsol so maybe there is an easy way to do it. I have a pipe with an internal helix structure which is repeated after a 180° twist. I want to use this symmetry to save computational power. Therefore I need to find boundary conditions, where the flow field at the outlet is equal to the flow field at the inlet.
I already tried periodic flow conditions but it resolves in a flow speed of zero since the inlet/outlet pressure difference is equal.
The model is attached. Do you have any suggestions for me?
Best regards
Jonas
