Which target length of finite elements is generally recommended?

Answer

Depending on the individual dimensions of the system, the following rule is recommended:

  • Generation of eight to ten elements between the boundary lines of a surface (see Figure 1), but at least four elements
It is also possible to use more elements, but it has to be considered that a finely meshed FE mesh lengthens the calculation unnecessarily and at the same time does not necessarily improve the quality of the results. Local FE Mesh Refinements may be recommended.

The FE mesh settings must be made under "Calculation" -> "FE Mesh Settings", see Figure 2.
