To model a pipe system, I made a simple setup in Inventor, exported as STP file and uploaded it to SimScale. However, I get problems during meshing. Below, you see a section cut of the model in Inventor. When I try to mesh it, it either takes very long and tells me that the mesh is too complex or it results in a cube. The model does not seem complex to me.
Would the physical size of the model be a problem? And what would be a solution in that case? I expect that water flows through these pipes will be different when I downscale the model.
