Error during Contact Simulation in GUI

[Priyanshu Agarwal]

Hi,

I'm trying to run the example TugOfWar_Complete in the OpenSim GUI (Ver 2.0.2) for inverse dynamics. I'm getting the following error even when the .obj file is present in the same folder with the model. Any comments on why would OpenSim throw this exception?

Exception:
Error loading mesh file: blockRemesh192.obj. The file should exist in same folder with model.
Loading is aborted.

Thanks.

Regards,
Priyanshu

Hi Priyanshu,

Can you try having the setup file in the same folder with the model? Are you using absolute or relative paths? Please let me know your directory structure.

Hi Ayman,

The simulation runs fine when I execute it using analyze command. However, when I run it from the GUI it fails even when the setup file is in the same folder. So, everything is in the folder C:\Program Files\OpenSim 2.0\bin including the OpenSim setup file, osim model file, .mot motion file, .obj contact geomerty file and other .vtp geometry files.

Hi Priyanshu,

Please report a bug and attach the files and a setup file to document what GUI is trying to do and I'll investigate.

Thanks,

Hi Ayman,

I have another question regarding this analysis. During inverse dynamics analysis does the simulation take into account the unknown contact forces.
