Re: FreeCAD as pre-post procesor for MBDyn

Another quick question. Is there any method that gets executed when the user clicks (single click) on a given object in the tree view? What I want to achieve: When the user clicks on an object, some other objects in the 3D scene get highlighted. Is this possible?

Re: FreeCAD as pre-post procesor for MBDyn

Yes, you are right, I think I need a bit more planning and less coding haha. Great advice, thanks!

Re: FreeCAD as pre-post procesor for MBDyn

Hi. Every time I make a change to the code, to test if it works as intended, I have to close FreeCAD and open it again, so that it "loads" the module with the changes... This is making me loose too much time. Is there a way to avoid this? Like forcing FreeCAD to load the module without closing it an...

Re: Multi Body Dynamics with FreeCAD + MBDyn

See how to define joints and constraints in ANSYS: https://www.youtube.com/watch?v=8HixzW8eFGs They also use those cylinders to represent the joints, and it also seems the bodies "crash", but the cylinders are only the joints for the MBD simulation, not part of the assembly. The same for the workben...

Re: FreeCAD as pre-post procesor for MBDyn

Will the recompute make any difference for a simple (non-parametric) object? To my understanding you recompute a parametric object every time one of it's parameters changes, so that the final object is actually affected by the parameter change. If the objects are non-parametric, as they are in my MB...

Re: Multi Body Dynamics with FreeCAD + MBDyn

Sorry, what do you mean by construction? I think herbk means if you were to physically build this machine, it would probably not work as this ideal model. Did you add collision detection yet, or not? Oh, I see what you mean. The parts that "collide" are not actually part of the model. The thing is ...

Re: FreeCAD as pre-post procesor for MBDyn

... https://www.youtube.com/watch?v=8dWsutquRi0&feature=youtu.be By the way, this bothers me although it doesn't seem to be a problem. In the tree view all your solids appear with the blue checkmark. This means that the body is in a "touched" state, and needs to be re-computed. Can you do a recompu...

Hi Jose,

Nice Animation, but your construction dosn't work... Have a look at the Axis of the big gearwheel. ;)

Multi Body Dynamics with FreeCAD + MBDyn

The first steps using my MBDyn + FreeCAD workbench to do a bit more complex simulations... very exiting!
