If your flow is circling back on an outlet, move the lid further away using a "dummy" extension pipe.
| Pitfall | Symptom | Fix | |--------|---------|-----| | Leaking geometry | Flow passes through solid walls | Use Check Geometry → close gaps with Extrude or Boundary | | Diverging solution | Residuals increase, NaN values | Reduce inlet velocity, coarsen mesh, increase relaxation factors | | Mesh too coarse | Pressure drop 30% too low | Enable automatic refinement, set min gap cells = 5 | | Wrong boundary condition | Recirculation at outlet | Extend outlet length 5x diameter, use Environment Pressure | | Steady state oscillates | Goals never flatten | Switch to Transient with small time step (0.001 s) | solidworks flow simulation 2012 tutorial.pdf
Many universities (MIT OCW, University of Alberta, TU Delft) hosted public mirrors of manuals for student use between 2012 and 2015. Use specific search strings: If your flow is circling back on an
