Thanks, Mohammadreza!

Has anyone tried creating the configuration of the InducedAcceleration component with code?

Best regards.

UPDATE,

I took a leap of faith and tested in OpenSim 4.5, but I got the same behavior in OpenSim GUI.

Best regards.

UPDATE, To make it clearer: analise3 = osim.AnalyzeTool('analise.xml') iaa = analise3.getAnalysisSet().get(0) CS = iaa.updPropertyByName('ConstraintSet') CSo = CS.updValueAsObject() CS_obj = CSo.updPropertyByIndex(1) # <objects> constraintR = CS_obj.updValueAsObject(0) #<RollingOnSurface ... > const...

Hello Mohammadreza, I'm getting the same behavior in OpenSim 4.4. It is definitely a bug. When I load the .xml, the IAA field is changed, clearing the information about the bodies in RollingOnSurfaceConstraint. errorIAA.png And it happens as well if you load the .xml file using the API in Python. I ...

Great. That would be awesome. If I could suggest, I also tried creating the .sto file for all contact forces in the model, and it worked well. Just create the .sto remember to insert [force] [Cop] [torque] for all contact geometry using only the halfplane (changing the signs of forces and torques). ...

Great! And... It worked!!!! For everyone interested in IAA analysis with OpenSim API after a Moco simulation, here are my top tips: Create a ForceReporter file of your simulation Follow the code in https://github.com/opensim-org/opensim-core/blob/main/OpenSim/Moco/MocoUtilities.cpp#L310 , but change...

Hello Ebenezer. I will take a wild guess ... When you load your model in OpenSim 4.4 (or higher) do you get this message? Updating Model file from 20303 to latest format... Loaded model 3DGaitModel2392 from file C:\OpenSim44_Models\Models\Gait2392_Simbody\gait2392_simbody.osim ControllerSet 'Control...

Hello Nick, My simulations are soon over, and I need to implement IAA right now (I have no more excuses for delaying this task :lol: ). I realized I could have access to createExternalLoadsTableForGait main variables with the ForceReporter. It gives me the Forces and Torques for Spheres and HalfPlan...

Hello,

I'm experiencing a very long processing delay. Last week, it was a matter of a couple of minutes, but today, it has been more than 12 hours since the upload.

What are the best time windows to run OpenCap to avoid these big delays or long queues?

Best regards.

Hi Xiaoxia and Matt, I thought I could help on this subject here since I will be starting a very similar project too. As Matt said, in OpenSim, the IK relies on weights to "trust" the markers' data. More weight equals more "trust." I regularly process mocap data (Vicon) with OpenSim. If the patient ...
