Hi,

What are the definitions of prism layer and inflation layer?

Thanks.

These refer to the region of closely packed cells near solid boundaries.

They earn different names like inflation layers because in that region you generally transition from a small cell next to the wall to larger cells as your progress towards the core flow.

Prism layer is so-called because of the method of projecting the mesh faces from the core mesh onto the solid boundary, resulting in prism shaped cells.

There are various names but a general way to refer to them would be "near wall cells" or "cells next to walls."
