Manual create FEM result when use ccx and gmsh

[felixlee868]

you guys

Can someone write article for introduction how to use gmsh and ccx and e,g tools to product FEM result?

I use MacOS, and The recently version of FreeCAD crash when I use FEM. I hope I can got some information about how to manual create FEM result when use ccx and gosh.

Thanks

[Kunda1]

I use GMESH and CCX

[bernd]

Does it mean you do not get ccx to run on OSX?

See this post if this is your problem. https://forum.freecadweb.org/viewtopic. ... 90#p508724

[felixlee868]

I am using Intel arch MacOS do testing for FreeCAD.
I found there some issues involved the FEM crash.

A) Can't setup Material Density value. ( default is : 0.0000kg/mm^3 )
B) Can't create mesh ( neither gmsh or netgen ), When create mesh for object, The freecad will crash.
C) spooles package not build library used for MacOS.
