Hi Lorenza,
This issue can occur when a muscle is either very short or very long. The excitations that go the muscle produce almost no forces. So essentially the muscle is in a (very) bad part of its operating range.

Hello,
I could not use LBFGS, PARAMOPT, IMDIF and LAPACK optimizers in CMC part of Opensim 3.1,
The software made an error like this one: "CMCTool: ERROR- Unrecognized optimizer algorithm: 'LBFGS'"
If there is any necessary dll files for these optimizers please help me to find them.
Thanks

Why are you trying to use a different optimizer than the default?
