Question

When creating an FE mesh for a solid, I get Error No. 2306: "Surface boundary is not closed at edges XX".
My solid has openings in the boundary surfaces. How can I solve the problem?


Answer:

A solid must always be completely closed. To clarify the problem, imagine filling the solid with a liquid. The liquid must not escape from the solid at any point.

The attached video shows how to easily and efficiently insert the missing surfaces.
