I am having an issue with my CFD of a bus. Previously I was having issues with the mesh with non-orthogonals. Once I finally got the mesh to work I ran the sim overnight has almost been running for 10 hours being stuck at 1 percent. The bus and boundary mesh are fairly large however I don’t think it should take this long. The run eventually ended with the max time being reached and it only calculated 6 seconds of flow. Possibly my parameters are off, looking for some help here.
Can somebody please help me out and provide a fix.
Thanks
Hi!
This is a cool geometry, and I see that you initially went for a transient study. Are you familiar with transient CFD simulations and its intricacies (Courant number, inner/outer correctors, PISO vs. PIMPLE, sensitivity studies, etc.)? A transient study with this model is not simple.
If you’re not familiar with transient studies, this CAD model is not a good one to start with the incompressible solver. This webinar here can help a bit, however I would suggest that you start with steady-state cases.
The incompressible LBM solver (optional solver for professional users) is more optimized for this kind of studies.
Cheers
