Hi,
I have been trying to create a mesh around a triangular cross section in ICEM CFD 16. Initially there would always be some triangular elements which affected the mesh quality. Then I tried with "O grid" which did give me a decent mesh but in fluent the solution diverges after a few iterations.

Files "My Mesh1" and "My Mesh2" are the ones with the ogrid.
File "Desired Mesh" is how I want the mesh to be.
Can some one please give me some pointers on how to go about this?
Thanks in advance.

I think there is no need of O grid

Hi Shubhankar,

I tried without the ogrid but I keep getting Triangular elements and min quality "-1" .


Could you suggest a method of doing this without the ogrid?
