CMC - How to decrease Residual forces?

Hi everyone, I'm trying to run the CMC tool but I obtain Residual values really too high (see plot attached) compared to reference values given from OpenSim documentation, even if after I have applied the RRA tool I obtain good Residual values (always according to reference values). Also, the kinema...

Using xsens data from c3d file

Hi, I'm trying to use Xsens data in OpenSim. I have my data in a c3d file and I used the c3dExport.m to obtain a trc file to run it on OpenSim. I applied the Scale tool and it worked but then I am having problems with the IK tool, the model is not walking in the right way. I'm wondering if maybe the...

IMUPlacer and IMU IK from Xsens data

Re: OpenSim Movella(Xsens) Dot IMU IK Heading Orientation

Hi,
I'm facing a similar issue with my project. I would like to know if you managed to solve the Xsens rotation problem that you had, and in case how did you solve it?

Thank you so much.

I am really struggling with the CMC tool because it never reaches a solution, it stops always at some point saying 'Unable to find a feasible solution at...
