Tgrid and ICEM CFD just work differently.

TGrid can not do post inflation at all. It was just designed for Pre-inflation.

ICEM CFD can do pre-inflation, but it is not our normal mode or best...

ICEM CFD Technology is used under the hood in ANSYS Meshing.

If you use "Pre" inflation, you are using TGrid Prism. If you switch to "Post" inflation, you are using the ICEM CFD prism algorithm.

If you are in ANSYS Meshing and you switch prism from "pre" inflation to "post" inflation, then you start to use the ICEM CFD prism meshing tool in ANSYS Meshing... Maybe that will work for you.

It depends on the metric and the solver, but generally speaking skewness and orthogonality are important for inflation.

However, having a thin layer does not always lead to issues like this. Is...
