Muscle Recruitment Criterion

Main Forum

Hi,
When I set the inverse dynamic criterion as MinMaxStrict, the following error occurred:
1.0) Inverse dynamic analysis…
ERROR(OBJ.MCH.MUS4) : D:/a…s/AMMR/A…n/E…s/G…y/GaitLowerExtremity.main.any : InverseDynamicStudy.InverseDynamics : Muscle recruitment solver : maximum number of setbacks occured
I 've no idea about this, so how to solve this prooblem?
Many thanks.

Hi Thomas,

Which model are you running? Which AMMR/AMS versions do you have?

Have you tried other solvers, e.g. the MinMaxAux? For debugging, you could also increase the order for a polynomial criterion to see how it behaves and if there are also problems showing up.

Best regards,
Daniel

Hi Daniel,
Thanks for your reply!
My model is GaitLowerExtremity and I changed the C3D data. And the 5.3 version is used.I have tried other solvers and got results.
Best regards,
