I was using freecad on windows and I developed a macro allowing me to generate a foil geometry, apply constraints to it and mesh it into the FEM workbench with Netgen (finesse = coarse, opimize = true, secondorder = true, maxsize = 1000). After some work, everything worked perfectly and my CalculiX files were correct. For information, my mesh still had about 15 000 nodes (which is very good for me)
Except that the rest of my work is done on a Ubuntu 20.04.5 LTS virtual machine. So I wanted to transfer my work from freecad windows to freecad linux. I was able to install freecad 0.20.2 and use the same macro (Netgen config : finesse = coarse, opimize = true, secondorder = true, maxsize = 1000) as on windows. And here is the problem: there are no errors but the mesh has now 400 000 nodes, which is much too fine for me.
I don't understand why I can't get the same mesh result as on windows ! I have not found any evidence of this problem on the forum.
My only clue is that when I run netgen through the terminal, I get this :
