Re: FreeCAD as pre-post processor for MBDyn

I made a mistake with the gravity units conversion It is fixed with commit 158.

To change the simulations parameters right click the simulation and select edit in the popup menu.

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. I made changes that I think will work(commit 153). I will no...

Re: FreeCAD as pre-post processor for MBDyn

Sorry. If you downloaded the the WB since my last post announcing the latest update. I found a bug that would not allow running an MBDyn simulation. It is fixed now

Re: FreeCAD as pre-post processor for MBDyn

There has been another update of the MBDyn workbench. It changes the way the MBDyn model is created. It Allows for you to save parameters for multiple simulations, like different initial values. Look for more ways the simulations may be setup in the future. We will update the documentation soon. Tha...

Re: FreeCAD as pre-post processor for MBDyn

Hello mfasano Thank you very much first of all for your help. I had configured the solver as you described and the _console.log exist. This time the content is as the following: reading from file "D:\Watch\pend\pend_hinge_input.mbd" warning, derivatives tolerance <= 0.0 is illegal; using default va...

Re: V0.19 Top Down Assembly Design Using Assembly4--Update #8

You have been doing great work for a long time. I have said I am always impressed when I visit the User Showcase, and your work does that. Your work with assembly 4 makes me confident about using it as a base for a multibody dynamics Workbench using MBDyn. MBDyn WB(shameless plug for my workbench)

Re: Exploding with Assembly4

I found if you change the placement and do an Gui.updataGui(), it will update the viewscreen with the parts placement but not do a recompute that would apply expressions. Do a recompute and they will go back to the assembled positions May-be, but when you use the "Transform" tool, it doesn't give y...

Re: Exploding with Assembly4

Maybe stop Assembly4 from re-solving the assembly temporarily so I don't have to release everything before I can transform it? Assembly4 uses FreeCAD's built-in ExpressionEngine to calculate the parts placements, and I don't think it's possible to temporarily deactivate them globally. I had asked a...

Re: FreeCAD as pre-post processor for MBDyn

Your video shows nice progress. When you have it ready I'll try the new tutorial and give feedback. Does your code structure allow easy addition of new joints? What is the issue you're facing with the total joint? Is the bug you are referring to is in the FreeCAD daily assembly4 workbench? The code...
