Hello all

I'm trying to use the call getTotalCentrifugalForces to attain the force contribution from Coriolis and centrifugal forces on a model through the MATLAB API.

I understand that this function and several other SimBody commands need to be called on a MatterSubsystem through getMatterSubsystem. However, any Matter Subsystem I acquire does not seem to have any corresponding methods that can be called from it such as getMatterSubsystem or getMobilizedBody for example.

The variable type also comes out to be: '1x1 SWIGTYPE_p_SimTK__SimbodyMatterSubsystem', which is suggesting to me that it's not being properly recognised by my MATLAB configuration for OpenSim.

Is it possibly I've missed a conficuration step for some of the more advanced API of SimBody? Or am I simply not accessing the Matter Subsystem in the correct way?

Cheers

The SimbodyMatterSubsystem is available in Matlab only in the OpenSim 4.0 bindings. Because OpenSim 4.0 has not been released yet, you would have to build from source: https://github.com/opensim-org/opensim- ... ource-code

Ah, I suspected this would be the case. No worries

Thank you very much for your help Christopher!
