<t>Hi Ayman.<br/> <br/> I have been taking down the osim file that I created piece by piece. And I keep getting a coupler deviation error (Coordinate coupler: unknown independent coordinate deviation). <br/> <br/> Using the debug tool at the higest setting I can see that the Osim file has been parse...

It continued to crash so I sent a copy of the model file and reported the bug. Thank you.

<t>Thank you Ayman.<br/> <br/> It is very helpful. Is there anyway to record a log of Opensim parsing through a model? I looked into the log files that are recorded in Opensim and they dont show what I want.<br/> <br/> When I open my model in Opensim, I get a message saying that a body is unassigned...

I have created an osim file with the additional body called forearm added. However when I try to run it on Opensim, the application shuts down completely before giving me an error message. What could be the possible error?

<t>Can you suggest an easier way of achieving what I am trying to do?<br/> <br/> I am trying to get the center of mass of the arm incorporated into the upper extremity model. The problem is that in my experiments, the arm is placed such that the two bones of the arm are parallel to each other.<br/> ...

The reason I am uncertain about the use is because the arm26 model that is one of the examples provided by Opensim, includes a coordinate actuator, a point actuator and a torque actuator. So I wanted to know whether these needed to be included in a model when you are applying an external force.

Thank you Ayman. I will modify the tree structure then inorder to try and achieve the result.

<t>In my experimental work I applied a torque at the shoulder and elbow joint of a subject. The actual torque value at every instant is stored in my data file.<br/> <br/> I wanted to know whether applying the recorded forces on the respective joints of the upper extremity model is sufficient or whet...

<t>In the upper extremity model, I would like to include an extra body so that it acts as a straight line joining the elbow joint to the hand. It doesnt have a visible object. However when I try to add it to the elbow joint it says that it is unable to add multiple joints to the same segment.<br/> <...

<t>I had a question about actuators and their uses that I am a little unclear about.<br/> <br/> I have a model where there are no actuators specified and the only forces present are the various muscle forces defined.<br/> <br/> I would like to apply an external force on various joints in the model (...
