I made a incompressible hex dominant parametric mesh on my FSAE car bluff body. The mesh was successful but on simulating, the results didn’t converge.
Hi there, thank you for using the forum This project has many simulations and runs inside, please let me know which one you are referring to so I can check.
The problem is with the Run 2 of “nose curve new”
There is not much to comment here from my side, the convergence can be improved if the mesh quality improves too. For example, you can enlarge the cartesian box used for the region refinement, and also increase the levels, etc.
However, my suggestion would be to use the standard mesher instead, like in this vehicle project: Aerodynamic Flow Behavior Around a Vehicle Tutorial | SimScale
Other than that, the setup looks alright, so you can focus on the mesh quality
Make sure to check this guide too: How to Check and Improve Mesh Quality | SimScale Documentation
