More mesh elements in region of part

Mods FEM
1

Hello,

I have a part on which I make some stiffness analysis. It is rather rigid with two flex elements. I want to have a detailed mesh on the flex elements, and a coraser one in the rest of the part, as there no deformation will happen. Is there a method to achieve that? One principle way would be to specify the element count on certain edges, is this possible in FreeCAD?

Regards,
Stefan

You could use the Meshregion and maybe the Mesh boundary layer…
see for icons https://freecadweb.org/wiki/FEM_Module

both work only with gmsh what is a pity since it is more sensitive of generating mesh than netgen

Use mesh region for this and yes it only works wit GMSH.

attached an example with various mesh regions (all kind of shapes could be taken) …
