Use case of Umberger2010MuscleMetabolicsProbe

Correct me if I am wrong but the use of Umberger2010MuscleMetabolicsProbe is not well documented.

I tried the following workflow (https://simtk-confluence.stanford.edu/d ... Sim/Probes). After running the Analyze tool the probe reporter .sto file didn't contain any result. After some search (https://github.com/opensim-org/opensim-metabolicsprobes) it turned out that the user must also append

Code: Select all

					<Umberger2010MuscleMetabolicsProbe_MetabolicMuscleParameterSet>
						<objects>
							<Umberger2010MuscleMetabolicsProbe_MetabolicMuscleParameter name="glut_med1_r">
								<!--Ratio of slow twitch fibers in the muscle (must be between 0 and 1).-->
								<ratio_slow_twitch_fibers>0.55</ratio_slow_twitch_fibers>
								<!--An optional flag that allows the user to explicitly specify a muscle mass. If set to true, the <provided_muscle_mass> property must be specified.-->
								<use_provided_muscle_mass>false</use_provided_muscle_mass>
							</Umberger2010MuscleMetabolicsProbe_MetabolicMuscleParameter>
							
							...
							

the Umberger2010MuscleMetabolicsProbe_MetabolicMuscleParameter structure for each muscle of the model. In case that someone runs into this situation this is the solution.

Please see the "Simulation-Based Design to Reduce Metabolic Cost" example in the Confluence documentation (https://simtk-confluence.stanford.edu/d ... bolic+Cost). Example files can be downloaded at the top of the page.
