Re: Why does FEM meshing doesn't generate volume elements in some cases
Sorry I didn't see that it didn't found your OpenCascade installation.
Mine is in /usr/local/lib/cmake/opencascade/OpenCASCADEConfig.cmake
It is really strange that the standard script didn't find it. Where is your original OCE installed ? I am getting worried that you had to remove it before installing the new one from OCCT.

Re: Why does FEM meshing doesn't generate volume elements in some cases
there was something with my occt comile ... OK recompile and make sure all cmake is fine ... It is now. I get linking problems ...
Searching the internet, I found this library was deleted during update from vtk 6.2 to 6.3 https://github.com/Homebrew/homebrew-sc ... ssues/2852
My first idea was get newer occt, but this is impossible ?! To get access to the github you need to singn an agreement. Hey I do not want write access I just would like to clone the repo ?!? Download of latest occt seams not possible ?!

Re: Why does FEM meshing doesn't generate volume elements in some cases
You could search the occ cmake variables, freecad does not need the vtk integration and basically does not use the visualisation at all, maybe you can simply deactivate it for compilation. Disclaimer: I never tried it

Thanks, I missed that snapshot button somehow ! Latest occt is compiling and has passed the linking vtkRenderingFreeTypeOpenGL problem. But it takes so long on my poor laptop ...sgrogan wrote:You can download snapshot of OCCT master here:http://git.dev.opencascade.org/gitweb/? ... git;a=tree

Hi sgrogan,
Yes they changed the name of the library, that is currently an issue within the CMake file of OCCT. So you can edit it by hand, and go straight forward.
@benrd, I hope that you have an SSD drive, as compiling everything is about 3 hours on my MacbookPro (latest version with 16GB)

Do you mean the Cmake file? If so I can't find this in any of the Cmake files.
Or edit the file name of the library. If so I assume both the .lib and .dll.

It took more than 4 hours on my 6 years old ThinkPad X301, but soon I will get hands on brand newest gerneration Thinkpad x1 carbon with ssd on pcie
Back to occt, taking the up to date snapshot it compiles flawless on debian jessie. I can run drawexe.
OK FreeCAD first without netgen !
cmake searches for OPENCASCADEConfig.cmake or opencascade-config.cmake but it is named OpenCASCADEConfig.cmake for me. I made a symbolic link by
cmake ../ gives now
OCE_DIR /usr/lib/x86_64-linux-gnu/oce-0.15
OPENCASCADE_DIR /usr/local/lib/cmake/opencascade
I tried to change OCE_DIR to opencascade libs with
I seams my lack off cmake to tell FreeCAD it should use my pretty new installed occt 7

Re: Why does FEM meshing doesn't generate volume elements in some cases
Hi Bernd,
This is because the CMake procedure is always looking for OCE before OCCT implementation.
So you can comment as a temporary fix into FindOpenCasCade.cmake the line 26 # find_package(OCE QUIET)
Then give it a try and you might be ok.
