Error in Inverse Dynamic

Dear Sir,

I encountered the following error after the simulation is done. I wonder if the results would be accurate since 7 out of 8 inverse dynamic was performed. If not, what needs to be done.

Macro command : InverseDynamicAnalysisSequence(7:8)> operation Main.Studies.InverseDynamicStudy.InverseDynamics

Macro command : InverseDynamicAnalysisSequence(8:8)> run

8.0) InverseDynamics (Operation: Main.Studies.InverseDynamicStudy.InverseDynamics):

The kinematic constraints have been resolved. …Initial conditions are fully updated.

Closing model…

Thank you in advance for your response.

Dear Pouyan Mehryar,

Whenever you see the following error message:
‘InverseDynamicStudy.InverseDynamics’ : Muscle recruitment solver : solver aborted after maximum number of iterations

It usually means that there are some missing forces in your models to run the inverse dynamics analysis. Or the strength of the muscles in your model are not strong enough to generate the required forces/torques.

If you want to ask us to debug your model, then please upload your model in the debug section:

Best regards,
