Re: Performing Inverse Dynamics via Matlab API

hi again, the ID batch is doing a great job, THANKS one more time for your help. Unfortunately I`ve another problem, now with the CMC batch. My plan is to run a set of simulations for 18 different motion-files and five different external load files. It seems that everything works fine, because when ...

Re: Performing Inverse Dynamics via Matlab API

... The error message seems to indicate that the file or one of the file names referred to inside it were not located correctly, which could be a Path issue (absolute/relative etc.) or could be that the files were found but the format is not what the code expects. ... Hi, Ayman! Many THANKS, you we...

Re: Performing Inverse Dynamics via Matlab API

Hi Ayman, and thanks for your reply. I found the method (setExternalLoadsFileName) and I tried to implement it in my Batch-code. But I´m very new in scripting and so I didn´t get the right way to use that method. So this is what I figured out ... ... % Setup the idTool for this trial idTool.setName(...

Re: Performing Inverse Dynamics via Matlab API

hi, and thx a lot for your response and the snippet of your code! Did I get it right, that your code is to create a externalLoads File out of you GRFforcedata depending on the motion and model used for ID? The problem of mine is, that i do not need to create the external load files (i did that via M...

Hopefully that works for you too. Also check that your template xml which you feed to the constructor is correct. The safest way is make a blank one in the GUI and operate on that rather than creating one in matlab.

Re: Performing Inverse Dynamics via Matlab API

Hi David, ... For the first part related to specifying ExternalLoads, I'd create an ExternalLoads object programmatically, add ExternalForce(s) to it then write it to a file, and then call setExternalLoadsFileName() on the InverseDynamicsTool with the name of the file you created. ... Best regards,...

"passive" ForwardDynamics

Hi, as part of my master thesis, I`ld like to simulate muscle force during training on a special legpress. Subjects are instructed to press (with 0%, 50% and 100% of voluntary activation) against the motor generated moving footplate of the legpress. The forces applied by the footplate and the path a...

Joint Reaction Analyze - CoordinateActuator

Hi everyone, I did some Joint Reaction Analysis with both, the results of CMC and SO. As mentioned in the Webinar ( http://www.stanford.edu/group/opensim/support/event_details.html?id=13&title=Webinar-Estimating-Joint-Loads-in-OpenSim ) i used the same files (Motion, externalForce, Actuators, ...) i...

Re: Drop Landing Model as example for Legpress Simulation

Hi Ayman, thx for your response. My aim is/was to situate my model on the plyo_block from the 3D Model Library. As rough approach of a legpress to get the forces in y direction. My consideration was that body forces due to gravity affects the cmc results of my legpress motion especially rect_fem. Fo...
