Oke i read the freecad forum now for a few days.
Now I don't understand why netgen doesn't work…
When i look at http://sourceforge.net/projects/netgen-mesher/ it looks like netgen have to work at all operating systems??
Or is this something in FreeCad? and when yes does it work also not work with OSX?
In eighter case how do i install the netgen/ gmsh?

i can't find anything here on the forum exept that mashing works or not works…

Thanks Jan-Bert

From personal experience,
I have both netgen and gmsh compiled and running fine in my Arch Linux machine.
However, compiling FreeCAD with NETGEN support enabled fails due to problems with SMESH and other stuff, so instead of wasting tiem trying to solve a problem that I do not fully understand (not a developer) I use psicofil's macro that allows FreeCAD to use GMSH.
Need help? Feel free to ask, but please read the guidelines first

on linux:
gmsh:
download and install any gmsh binary and the gmsh macro of psicofil and freecad binary

netgen:
you need to compile netgen for your system linked against the same occ or oce freecad is linked to. compile freecad with netgen enabled.

as drei stated a fail with the last one is common :( . That is why gmsh is used very often :) .
