Hi, I am performing a static analysis of a 6DOF tibiofemoral joint with ligaments and articular contact model subject to external forces using the ForwardTool. I run the simulation and postprocess the results through API in Matlab. Actually, I'd like to estimate the individual contribution of all fo...

Thanks Ayman

Hi,

I am using a force defined by a plugin and I would like to load a model containing this force in Matlab.
Is-there any way to load the specified plugin library in Matlab?

Thanks for your help

Regards,

Romain

Hi Ayman, Indeed, in the release 3.0.1, contact force classes such as ElasticFoundationForce and HuntCrossleyForce are exposed to the Matlab interface. However, ContactParameters objects are defined in SWIG type so i cannot manage to tune these properties from Matlab. Do you know how could I figure ...

Hi, I want to add some contact forces to my model through OpenSim API in Matlab. However, it seems that some child classes of Force (e.g. BushingForce, ElasticFoundationForce, HuntCrossleyForce) are not imported with the modeling module (import org.opensim.modeling.*). Any idea about how to add this...

It works now. Thanks Ayman.

Hi, I want to estimate some knee ligaments properties through an optimization process using API in Matlab. First, I need to obtain the knee ligaments moment arms using the "ComputeMomentArm" method in the "Ligament" class. My code to get the moment arms in the default pose is: myModel = Model('myMod...

Hi, I had a similar problem with version 2.4.0. I realized that I was using Matlab 64 bits while OpenSim was a 32 bits version. Now it works fine with Matlab 32 bits. Also make sure that you have set up Matlab to access the Java wrapper to Opensim. It is well explained in the readme I enclosed given...

Hi, Does anybody knows if it exists an OpenSim plugin that allows an optimization of functional parameters along with IK. This method was described by Jeff Reinbolt (Determination of patient-specific functional axes through two-level optimization,2005). I suppose this is a very straightforward way t...

Hi, I'm new to c++ and even opensim and I am actually practicing with API examples. I am trying to output controls to a "controls.sto" file. It worked perfectly for the MainExample using osimModel.printControlStorage() after integration, but using the same method within the Arm26Optimization example...
