Hi Everyone, I want to generate static optimization file of .mot 8 seconds flexion movement, But OpenSim do not complete the process and crashes.
I tried in other computer (i7 12 32GB RAM) but the same error occurred

Hi Lisias,
The muscles around the shoulder don't look right to me. Have you checked the moment arms for the muscles in the model? Do they all have reasonable values and no discontinuities?
Best,
Nick

Hi Nicolas, yeas the moment arm is correctly.
I need to transfer muscles to radius/ulna, simulating coto surgery, then I start in blana model, transfering braquiohard_1 to radius object how attach. But when generated bic_l force muscle, my graph is how demonstrated.

Hi Lisias,
The biceps force doesn't look very smooth, which suggests there might be an issue somewhere. Could you also plot the moment arm of the bicep relative to the elbow joint angle?

I am forwarding the .mot and data file generated by Inverse Dynamics to your analysis

Hi Lisias,
I'm not sure what this plots mean without axis labels.

Nicholas i found one problem in .mot file.
Then i created a new file and generated biceps force, but this new file is ony to test and no real datas.
