CoordinateActuator forces reference frame
Hi, When running the Inverse Dynamics Tool one gets the forces/moments of the CoordinateActuators. I tried to find in which reference frame these forces/moments are expressed but could not find this in the documentation. My guess would be the parent body of the respective joint on which the Coordina...

Re: Marker or point location in API
Hi Ayman,
Thanks for the reply! I already found and figured out the ways to transform the points to another body.
Best regards,
Erik

Marker or point location in API
Hi, I would like to get the location of a point on a body through the API. The location of the point of interest should scale along with the body it is attached to. I haven't found a way to define a point on a body so the only option I could think of is to define a marker on the body and get its pos...

Re: Implementation of Static Optimization
Daniel thank you for sharing your code. I think it will help me later on to get data from/feed data to the optimizer at intermediate levels and not just at the end. In the mean time I think I found the code which can help me to build a modified optimization. I downloaded the source code for OpenSim,...

Implementation of Static Optimization
Hi all, I would like to perform an optimization with the OpenSim model using the API, preferably through MATLAB. However, I could not find out how I get all the necessary data from the model. My thought was to start from the Static Optimization from the Analysis Tool but I cannot find its implementa...

Re: OpenSim crash in IK analysis
Hi James,
Thank you for the suggestion.
I tested a few times and so far it seems to solve the problem with the IK tool. Thanks!
Best regards,
Erik

OpenSim crash in IK analysis
Hi all, I am trying to run Inverse Kinematics Tool in OpenSim 3.1.0 but I encounter some problems. First of all it does not auto fill the weighting section when loading the setup file. IK doesn't run without because then I get the following in the message window: Loaded model subject01 from file C:\...

Re: Crashes During Joint Reaction Analyis
I have a similar problem. I run the Analyze Tool for Static Optimization from MATLAB.
I call the Analyze Tool in a loop but in the second iteration MATLAB suddenly shuts down. My error report looks similar to that from Liying, see attachment.
Best regards,
Erik

Model offset during scaling
Hi all, I encounter a problem which I think is GUI related. When I am working on scaling a model, the new model appears in the view with a slight offset. Looking at the model and navigating in the view after a few scaling iterations becomes impossible as the model is no longer visible in the view. S...

Re: Optimization constraints
Hi Ayman, Thank you for your reply. I successfully build the coordinate limits in the model. However, I can't seem to get the limits working by constraining in the optimization instead of in the model. I wrote an inequality constraint by getting the elbow coordinate value and specify that it should ...
