mesh problem

Hi
I am using Comsol, heat transfer module. My geometry has a thin layer inside a box. I used swept mesh for thin part however for all box I used Tetrahedral. But when building mesh I got the error of "Try converting to triangular mesh on these faces" ... I attached my file. It is so appreciated if you let me know your idea.

Hi
The boundaries of the thin layer which is meshed with swept mesh exhibit outwards rectangular elements. It is not possible to continue from rectangles to prisms or tetrahedra. To solve the problem you have to make a thin layer which covers the entire 80 x 130 mm area. Mesh that with a swept mesh, so now only triangles are seen outwards, and the rest can now be meshed with tetrahedra or whatever. Geometrical domains do not need to coincide with physical domains, you define in the physics nodes which domains belong to which physics.
Wish this helps
