I dont know how to do? In my previous answer, I posted a link pointing to a similar analysis. Following this, you should be able to read: Tetrahedrons should have a maximum aspect ratio of 2. In your vid one can see: Screenshot 001.png That's too bad! :( Please have a detailed look into Gmsh proper...

Looks like a duplicate from this: ;) https://forum.freecadweb.org/viewtopic.php?f=3&t=58671 Screenshot 003.png Screenshot 002.png If you aren't looking for a contact analysis, you need of course a single solid (Fusion) to obtain one mesh instead of multiple even incoherent meshes. file: _FEM_noB...

It's working fine on win 10

With Downgrade from Lattice2 WB, parametric is preserved, in opposite to Downgrade from Draft WB.

Could only get frontistr AMG/CG to finish


Where is the beaf?

You can simply explode sketch with DowngradeToEdges using Lattice2 WB and apply BooleanFragments afterwards.

Applv an appropriate view for selecting all balls, using menu Edit->


Forward selection to PartWB->Defeaturing
