CFD - meshing a prism layer on a zero thickness surface

[Simon Williams]

Hello Everyone, I was hoping someone could help me out a little.

I am trying to CFD a simplified half model of the UWA car and I am representing the side pods and chassis as a zero thickness surface. I am using ICEM and Fluent as a mesher and solver respectively.

When I come to create a prism layer on these zero thickness surfaces, highly skewed elements form at the edges of the surface. I've looked at the ICEM help file and couldn’t see a solution there. I've tried reducing the element size along the edges, which shoots the total cell count through the roof and isn't really desirable.

Any suggestions? Magic button perhaps??
Cheers
Sim
