DeGrooteFregly2016Muscle exportTendonForceMultiplierToTable

[Xiao Hu]

When I am exporting tendon force multiplier in the DeGrootFregly2016Muscle, I get NANs. Does anyone know why? Thanks!

Code: Select all

import org.opensim.modeling.*
DGF_model = DeGrooteFregly2016Muscle();
DGF_tendon_osimDataTbl = DGF_model.exportTendonForceMultiplierToTable();

Example output shown below:
