How can I retroactively adjust my surface model with regard to the finite element size and avoid too high total number of elements?

Answer

Basically, the surfaces of a model have the FE size that was preset in the general FE mesh settings.


You can locally add "FE Mesh Refinements" to a surface model.

This has the effect that the general finite element size is kept in the FE mesh settings, but the mesh is locally refined so that more accurate results can be expected from the calculation.


In this case, the FE mesh refinement can be performed on nodes, lines, and surfaces. The setting for this can be found in the "Edit" dialog boxes of the node, line, or surface.

By using the local FE mesh refinement, it is possible to keep or even increase the general FE mesh size. Thus, it is possible to keep the total number of elements in the model relatively low.
