Maybe for this explicitly architecture/bit size dependent code one should use the best-practice solution in C++ (namely explicit usage of those 64bit types, like mentioned in the stackexchange discussion) and put a comment into the code. (I have the feeling that just changing the size to `unsigned l...

Auch auf die Gefahr hin, jetzt etwas off-topic zu sein: Als das Thema Bruchmechanik aufkam, kam mir folgendes FEM-Programm in den Sinn: http://www.impact-fem.org/ Es ist wohl open-source und auch fuer die Simulation von Abformung geeignet. Ich hab aber nur kurz durch die Tutorials gescrollt und kein...

Ah I see your point . Thanks for the file! So in principal I have to check for the second order elements to be sure whether there is a second order mesh or not.

Best wishes Johannes

sounds good to me. Should I put these into another sub directory or should they stay at the import/export file location? Are the helpers really Fenics specific? Some of them are, some are not. OK, I will first check whether there are Fenics specific helpers. If not I will implement the helpers into...

Hey bernd, I just coded a mesh export for Fenics for a new format (.xdmf, which is state of the art) in a macro and I saw that there is a lot of stuff to be done which is the same like for the .xml. Other stuff is very different, though. For the implementation in the source tree I would like to sepa...

I just built the latest FreeCAD source on my thinkpad with OS: Linux Mint 17.1 Rebecca Word size of OS: 64-bit Word size of FreeCAD: 64-bit Version: 0.17.10492 (Git) Build type: Unknown Branch: master Hash: 58ed7c3688beb98ef89994919eddd9a4d0dd55e2 Python version: 2.7.6 Qt version: 4.8.6 Coin version...

BTW: What I do at the moment is use GMSH for all kind of display tools in the regard of a FEM mesh. So you export the mesh into a format readable by GMSH and do the visualization there? I thought about using GMSH either, but from my first impression the GMSH gui behaves strange ;-) Although GMSH wo...

Hi bernd, yeah I searched the ViewObjects methods and variables for an appropriate function, but I didn't find something. I know the following request is a huge amount of work, but I will ask you anyway :mrgreen: : Is it possible to add this functionality at the C++ code level to the FemMesh object?...

Hi HoWil, thanks for the compliment! :mrgreen: The conversion from 1st to 2nd order elements is still a topic. As far as I know, Fenics only can read 1st order elements from its mesh format. Afterwards you may convert the elements to second order by the step, you suggested. Anyway, there is still th...

10dd719 d751423 Ah nice! Thanks bernd for your support regarding the implementation. First part of communication with Fenics done :mrgreen: . I just deleted my local feature branch. The next feature would be the implementation of cell and facet functions which are created by FreeCAD. I saw that we ...
