I am following the instructions to build cgx_2.17. It says that I can additionally/alternatively build ng_vol instead of the supplied tetgen because it allows tet-meshing with a target-element-size. Therefor, according to the instructions, a source file shall be replaced:
Replace the src file with the one located in the folder cgx_2.17/netgen and build it in the netgen directory.
However, there is no cgx_2.17/netgen directory. Has ng_vol become obsolete?
hi,
interesting features were i also seeking for. especially in quadrangle dominate capabilities of Netgen.
someone stored CGX source codes at GitHub, seems right ng_vol.cpp files did not available since 2.12 versions.
i did not know the compatibility issues with latest version of CalculiX GraphiX, it need a try.
best,
Tetgen supports a target-element-size out of the box. Only the netgen mesher would need an update. I include the netgen files in 2.18 again.
I add tetgen 1.6 packages to mingw from msys2:
