Re: Calling multiple instances of OpenSim from MATLAB

Please ignore my last reply. A night's rest was all I needed to work out the issue. Everything works fine now. Thanks again for your help!

Re: Calling multiple instances of OpenSim from MATLAB

Thanks for the feedback. I have the Parallel Computing toolbox, and got the 'parfor' method functioning. I want to run analyze.exe for two .osim models in parallel. Below is some pseudocode: parpool('local',2); parfor subjects 1 & 2 Modify .OSIM & Setup files % Run static optimization evalstring = s...

Calling multiple instances of OpenSim from MATLAB

I am running a batch of OpenSim Static Optimization jobs via MATLAB using eval(): evalstring = sprintf('!analyze -S %s', fullPath) eval(evalstring); The number of jobs is sufficiently large that I would like to run multiple jobs simultaneously. I think that I can do this using parallel processing on...

Re: Static Optimization error with additional actuators

Thanks for the recommendation. Dropping the optimal force eliminated the error messages. I would like to better understand why the combination of an upper bound and a large optimal force caused IPOPT's restoration phase to fail. The optimal force was not an issue until I created this limit on the ma...

Static Optimization error with additional actuators

Hello, I am trying to apply a <CoordinateActuator> with a large optimal force to the Crouch Severity Simulation data set available on the SimTK website. At this point, I have added one <CoordinateActuator> acting on the right and left "ankle_angle" joints (see sample code at the end of the post). Si...
