Precedence Rules
You can reuse the surfaces used for defining Thin Solid mesh controls for other mesh controls or idealizations. For example, a shell pair can be defined on the same surfaces used for Thin Solid mesh controls. In such cases the following precedence rules apply:
1. If there is a conflict between a shell pair and a thin solid mesh control, then the behavior is as follows:
If the geometry type is solid, the shell pair is ignored and the thin solid mesh control is processed. If the geometry type is Solid-Midsurface or Midsurface, the shell pair gets the precedence. Some of the paired surfaces of the Thin Solid AutoGEM control are compressed due to the shell pair.
If all the surfaces belonging to the Thin Solid AutoGEM control are compressed due to the shell pair, the Thin Solid AutoGEM control gets ignored.
2. If conflicting thin solid pairs are created that is if one thin solid pair is on one of the side surfaces of another thin solid pair, it is impossible to mesh the model. In such a case, an error message is displayed when meshing the model.
3. All mesh controls which control the mesh size or distribution have precedence over Thin Solid AutoGEM controls.
4. If a thin solid control is defined on the side surfaces of a prismatic element control, then both the prismatic element control and thin solid control are ignored. Hence, Thin Solid and Prismatic AutoGEM controls cannot be applied in the same volume.
