Re: Determining Muscle Forces From MOCO Solution

Hi Nicholas, Thank you again. Just to clarify, do I need to change my original simulation (with all the set up, bounds, etc) to a MocoStudy instead of a MocoTrack and run it again in order to get these outputs? Or can I just set up a simple moco study (similar to what I did above) and use the soluti...

Re: Determining Muscle Forces From MOCO Solution

Hi Nicholas, Thank you for that, this is what I am looking for I believe. Is there any chance you could please provide some formatting assistance for me? I am using MATLAB for this project and I cannot find an example of how to use "MocoStudy::analyze()". I Have tried multiple set ups but whenever I...

Re: Determining Muscle Forces From MOCO Solution

Hello, Wouldn't using this muscle analysis tool defeat the purpose of trying to find the muscle forces from the tracking simulation? Or am I misunderstanding this. It just seems odd that almost every example simulation code I have seen uses the operator "ModOpIgnoreTendonCompliance" when doing this ...

Re: Determining Muscle Forces From MOCO Solution

Hi Pasha,

Thanks for the reply.

How would I go about finding the normalised tendon force? Would I need to change something in my simulation code in order for it to be included in the output?

Cheers in advance,
Brodie

Determining Muscle Forces From MOCO Solution

Hello, I am trying to make sense of the outputted muscle forces from a tracking simulation I have run. As an example I will use the left soleus muscle. My main question is, what does the value of /forceset/soleus_l represent? Is it the percentage of the maximum possible muscle force for that muscle ...

Double Peak GRF's When Using A contact Model

Hello, I have been trying to run a 3D walking tracked simulation that is based off of the 3D walking example however I have replaced the GRF reference file with a six sphere contact model found here: https://simtk.org/projects/predictsim_mtp (see attached image for reference). The simulation runs an...
