Re: FreeCAD as pre-post processor for MBDyn

Thanks JamesLiu. I just downloaded 0.2 and checked. This error vanished and new error started. I will check further. For information, the error is: Running the Python command 'MBdyn_AddStaticBody' failed: Traceback (most recent call last): File "C:\Program Files\FreeCAD 0.20\Mod\freecad-mbdyn-d...

Re: FreeCAD as pre-post processor for MBDyn

Dear All, Any idea how to constraint a point (or edge) always on an edge (or surface) in FreeCAD? I know this may not be purely related to MBDyn forum, but MBD people will know this better. This is similar to contact constraint. I am trying to figure it our but no results yet. Thanks in advance. &qu...

I really appreciate the work !

Another thing, may be trivial. It gives a warning when I switch to MBDyn WB.

Re: FreeCAD as pre-post processor for MBDyn

I think there was one person Jose who was much ahead on this. But he is not on the forum now a days. He has lots of code on this. Hopefully he starts again. If mfasano gets his code, it will be very helpful.

I want to try following tutorial.

Re: FreeCAD as pre-post processor for MBDyn

Okay, I will try new commit. Another feedback is, it is putting a word 'offset' in the 'In-line Joint' script. This seems to be a syntax error. Let me know if I am wrong. joint: 3, in line, 3, position, null, orientation, , 0.0, 0.0, 0.0, 2, offset, 0.0, 0.0, -3.0;

Re: FreeCAD as pre-post processor for MBDyn

Excellent... Very good Job. I hope it matures further. I managed to complete the simulation. When I change the gravity value to 9810 mm/s2, the run diverges. I had to play with simulation settings to converge. In the end, it converged. Run converges very well on settings mentioned on tutorial with g...

Re: FreeCAD as pre-post processor for MBDyn

Hi, I am trying to run the pendulum tutorial. Earlier WB was not running the simulations, which seems to be solved. I am facing two problems. 1. I am not able to add gravity. It is just adding blank entry. It is giving me following error. 'Traceback (most recent call last): 14:21:41 File "E:\Fr...
