I tried some example in cfdof workbench but it has error with multiphase (air-water) flow model.
I made the model "filling of tank" simililar to https://forum.freecadweb.org/viewtopic. ... 47#p194045
The model is attached.
- blueCFD-core: installed via freeCAD
- The calc. conditions are set in cfdof workbench only. I don't edit the openFoam files directly.
- Mesh/walls seems no problem since the solver runs in single phase flow.
- Boundary conditions: Inlet= velocity, Outlet= pressure
