Hi Ayman,

That was very helpful. Thanks for the reply. I see a lot of features in OpenSim, however the OpenSim UserGuide doesn't include anything about their usage. Is there any separate documentation for these features?

<t>Hi,<br/> <br/> I have a model in which I need to constraint the distance between two points which are on two different bodies. Both the bodies have rotational joints about two other bodies. Is it possible to define constraints involving multiple DOFs in OpenSim?<br/> <br/> Regards,<br/> Priyanshu...

<t>Hi,<br/> <br/> While performing static optimization to calculate individual muscle forces the lock/unlock state of unactuated joints makes considerable changes in the muscle forces. When the analysis is carried out the joint coordinates are already set (no change in value for unactuated joints) i...

Thank you Ayman for sharing the document. It is very useful.

<t>Hi Ayman,<br/> <br/> Thank you for your help.<br/> <br/> I have one more question in this regards. I have defined a constraint between two bodies such that the angle of two are always constrained. In such a scenario if I perform the Inverse Dynamics Analysis, how the force interaction between the...

<t>Hi,<br/> <br/> I have a problem in which the model has a closed kinematic chain. It comes out that for modeling such a problem two joints need to be associated with a body. However, Joints in OpenSim only supports one CustomJoint within the body definition. Is there a way to simulation such a pro...

Hi,

Is it possible to employ springs that connect two bodies during the inverse dynamics analysis? Furthermore, the spring force should be a function of the displacement between two bodies.

Thanks.

<t>Hi Ayman,<br/> <br/> While performing the inverse dynamics analysis I obtained one of the results file as "Modelname_Muscle_Analysis_Force.sto". When I plotted the data against time, I obtained very high values which seems to be no way the muscle forces. What data does this file contain?<br/> <br...
