Documentation for RaiseFallProfileFunction

Dear Thomas,
The documentation for the RaiseFallProfileFunction doesn't contain its details and attributes. Can you please provide this information?

static optimization failed at some instances

Dear All, As I was running a static optimization for loaded walking, optimizer failed at some instances with error messages similar to below. I have appended reserve actuators. This happened for about 2% of time steps. Is this OK? Any other suggestions? SimTK Exception thrown at InteriorPointOptimiz...

Re: Asymmetrical muscle activation in exampleMocoInverse

Thanks Nick. I will try with larger weight. Originally I was doing MocoInverse in Matlab with the model and data from the Moco Paper (Prescribed walking example), For which, I got similar kind of full activations for gaslat, bfsh,sart, glmin, psoas and tfl. I am wondering if you also got similar act...

Re: Asymmetrical muscle activation in exampleMocoInverse

The following seems to be the reason, as I saw in another post by Nick. "Without a periodicity goal or some sort of initial bound on the initial muscle activations, they are free to activate as much as they want at the initial time point. The activation state variable at the initial time is basicall...

Asymmetrical muscle activation in exampleMocoInverse

Hi all,
When I ran the exampleMocoInverse code, I see some muscle activations are highly asymmetrical with full muscle activation (for example see the pic below). What is the reason for this and how to overcome this?

Joint Reaction Analysis from Moco Solution

Hi All, I am performing a joint reaction analysis from Moco solution using the AnalyzeTool. I specify the controls file under control set, then a states file and grf file under external loads file. I don't specify forces file under JointReactionAnalysis. Is this right? I want to confirm. Thanks, Kar...

Re: Error in Muscle Analysis

I couldn't resolve this issue still. I will be grateful, if anyone has some suggestion to overcome this issue.
Thanks,

Accessing kinematic states when using inverse.initialize()

Hi all, When we create a study using inverse.initialize() and solve, the solution file doesn't seem to contain the kinematic states in it (The solution of a MocoInverse has the kinematic states). If that is true, how to get a states/solution file which includes the kinematic states. I need them for ...

Error in Muscle Analysis

Dear All, When I was doing a muscle analysis using the analyze tool with a setup file in Matlab , I got the following error. It was with 'DegrooteFregly2016Muscle'. I was able to do the muscle analysis with a different model with 'DegrooteFregly2016Muscle' earlier. WARNING- MuscleAnalysis::record() ...

Re: Query related to UMocoD Project

Dear Ross Miller, In the 'goWalk_v2.m' code, it was mentioned that "Starting from the initial guess provided and running this code as-is, the optimization converged after 100 iterations". When I ran this code as is with the provided initial guess, it converged after 364 iterations. Does the hardware...
