Unstructured mesh (on Gridgen) doesn't run in FLUENT
I'm not an expert using unstructured meshes on FLUENT. The thing is that I had to make a hybrid mesh (prisms + tets) amid my (3D structured) domain in an attempt to reduce the number of nodes. So what a I did was to extrude the unstructured mesh on the walls and to initialize an unstructured block on the core of the block.
When I run a 1st order SIMPLEC with a k-e closure, everything is fine. But when I try to shift gears to a 2nd order scheme the case automatically diverges. It doesn't even bother to make one time step.
Thanks in advance,
