Hi, Iím trying to simulate air flow through a diffuser I have created for a wind turbine. Iím having trouble creating my mesh in that when I do, it meshes the diffuser but the domain is a very coarse mesh (or so thatís what I think). Does anyone know why this is so?
Also on my shroud itself there are thin vents any recommendations on how to make an accurate mesh on this?
Thanks! Would be a fantastic help

Your meshing pipeline does not contain a volume mesher (aside from the thin mesher, but you cannot use this by itself), so you do not have a mesh. You're just looking at the surface.

I would suggest you take a step back and go through some of the meshing tutorials before attempting your own geometry.

Thank you for your response. Iíve done the tutorials and Iíve used a polyhedral mesh but Iím still having the same problem
