Calculations in SmoothSphereHalfSpaceForce
Hello, Thank you for OpenSim Moco. It is a great platform for faster simulations. I am using the Hunt Crossley Force using the SmoothSphereHalfSpaceForce in Moco. On Github, I was trying to find the code where all the calculations in this code, but I could not find them. For example, the code https:...

Re: HuntCrossleyForce Implementation in Moco
Something that I did observe was that if I add the hunt crossley force in a function and call that function again and again, MATLAB tends to crash after a few calls if the safeDownCasts are there. If I remove the safeDownCasts, it works fine. I do not know what causes that, it could be just my compu...

Re: HuntCrossleyForce Implementation in Moco
Thanks for the answer Aaron. It seems to work. Cheers!
Chris, Thanks for response as well. I will post if I find that one works better than the other.![Smile :)](./images/smilies/icon_e_smile.gif)

HuntCrossleyForce Implementation in Moco
Hello Moco admin, First of all, Thanks for creating Moco. It makes direct collocation so much more user friendly. I am trying to use the Hunt Crossley Force. Based on the reading some literature (Serrancoli et al 2019 [Subject-Exoskeleton Contact Model Calibration Leads to Accurate Interaction Force...

Re: how to get states from .mot file using API commands?
Thank You, Christopher. It seems to work, but I have a question though. I calculated the moment arm using three different ways 1. In the plotter in GUI using the _ik.mot file 2. In MATLAB using the _ik.mot file 3. In MATLAB using the _states.sto file (exported by performing RRA on the same motion). ...

Re: how to get states from .mot file using API commands?
Thanks Christopher. I looked up in the API documentation and is said that the use in python is something like this: import opensim model = opensim.Model("subject01.osim") sto = opensim.Storage("subject01_states.sto") states = opensim.StatesTrajectory.createFromStatesStorage(model, sto) so for MATLAB...

Re: how to get states from .mot file using API commands?
Thanks for the response, Christopher. Based on the link, it seems like I need to use StatesTrajectory.createFromStatesStorage(). So is it anything like this? import org.opensim.modeling.* modelFile = 'ULB.osim'; osimModel = Model(modelFile); motFile='mymotion_ik.mot'; coordinateSto = Storage(motFile...

how to get states from .mot file using API commands?
Hello all,
This might be trivial for a lot of you, but I am new to using API/Doxygen commands in MATLAB. I am trying to find muscle moment arms using the command
Muscle.computeMomentArm(state, coordinate);
How can I find the "state" from a .mot file?
Thanks!
Dhruv
