Re: FreeCAD as pre-post processor for MBDyn

This is an idea I´ve had in mind for a while. I have seen people struggle to write an assembly workbench for FreeCAD for years. There is assembly 2, but it only works for assembies with few parts and it often cannot solve relatively complicated assembies. Assembly 4 is a nice tool, but the lack of a...

Re: FreeCAD as pre-post processor for MBDyn

You may want to skip the animation algorithm (animation.py). I programmed it using python lists for the position and orintation data, as well as for the animation of the force vectors and the reaction forces. This works, but is too complicated. I am now migrating the animation.py file to numpy ndarr...

Re: FreeCAD as pre-post processor for MBDyn

It does not work well on 0.18. All the examples were created and tested on 0.19. I have just tried on a fresh Ubuntu 20.04 installation with the FreeCAD 0.19 AppImage and it worked. Same on Windows (FreeCAD_0.19.23578-Win-Conda_vc14.x-x86_64). On Windows is easier because one does not need to insta...

Re: FreeCAD as pre-post processor for MBDyn

First of all,thank you josegegas. I'm using Linux Mint 20.1 and i had some errors because mbdyn is installed in /usr/local/mbdyn .

Re: FreeCAD as pre-post processor for MBDyn

Hello all. Just one quick question. When one writes the input file for Calculix using the FEM workbench one can see/edit it within FreeCAD, using an "editor". I assume the input file for Calculix is a simple text file? If so, would it be possible to open the input file for MBDyn, within FreeCAD, usi...
