Re: RRA failure

Ayman, I corrected the differences between my current and previous models that I mentioned in the last model. However, the RRA stage of OpenSim continues to fail (with the same message). I have attached the files I am using in the ZIP folder below. If you could take a look at these and let me know i...

Re: RRA failure

Thank you Ayman. I was unaware that control constraints were unnecessary / unsupported for RRA. I removed the call to that file from my setup. However, the process still failed in the same manner even without the control constraints file. When this was the case, I tried performing RRA with my curren...

RRA failure

I have a set of jumping files which I have successfully run through the scaling, IK, and ID tools of OpenSim. However, when I attempt to run the RRA tool, the simulation stops at the first time point. I have pasted the output dialogue from the message box below. Also, I have already upgraded to the ...

RE: Creation of Virtual Markers

Unfortunate. I was afraid that was going to be the response. Thanks for the advice.

Creation of Virtual Markers

<t>I want to create virtual markers within my model. The locations of these markers would be calculated in reference to the positions of actual markers loaded from my motion data. I then want to use these virtual markers as reference points during scaling. Is it possible to create such markers withi...

RE: CMC - optimizer failed (status 3)

<t>Hossein,<br/> <br/> Thank you for your reply, I have worked with adjusting the .OSIM file to increase maximum isometric force across the muscles. This did resolve some of the CMC simulation failures.<br/> <br/> However, this was not true for all cases as some files still crash the simulation. Sin...

CMC - optimizer failed (status 3)

<t>OpenSim team,<br/> <br/> I am experiancing an issue with the CMC tool. When I attempt to simulate trials based on jump-landing or sidestep-cutting kinematics the process fails to complete and I continually receive the error "Optimizer failed: Ipopt: Search direction becomes too small (status 3)"<...
