Quad shells instead tri shells in Batch mesh
 

I'm trying to develop a tri shells mesh for CFD analysis using Batch mesh automation. But in some surfaces, ANSA generates quad shells instead of tri shells.

How to solve that?

There is button to split all quad shells to tria.
Go to the Mesh Module on the right > Elements > Split Quads >Select the mesh of your model
After clicking okay or middle click, all quad shells will be split to Tria
