Hi there,
I plotted the result of ID in my model and tried to compare it with the Rajagopal model, but in some sections of the graph became reverse.
I used rectify in the setting but it didn't work. How can I mirror it and overlap them in OpenSim plotting?
Thanks

Re: distance between two points
Hi Nicos, Exactly, you are right. So, let's return to my first question and conclude this subject. I want to calculate the distance between two points, one in the femur and the other in the tibia. I used point kinematic to measure the distance. and I just inserted the knee flexion-extension coordina...

Re: distance between two points
Yes, I just made a sample file with some different numbers. I attached the file. Because I just want to follow the femur and tibia, I just digited the 'knee_angle_r'. The time will be synchronized with the setting. I checked it. The question is why when I choose a point in 'body_name' femur there is...

Re: distance between two points
Yes, I did. I define a '.mot' file in the main setting and defined the point kinematics according to the specified numbers. I attached the file screen of the setting and results. I don't know why there are no changes in the graph? Is it can be because of the proximity of the points to the femur or r...

Re: distance between two points
Thanks a lot Nicos for your advice. It was really helpful. I did it, but there is something which I didn't get it. When I choose Femur as a body and select the ground as a relative to the body, after plotting, the states(0,1,2) didn't change and they are straight lines. is it related to my selected ...

Re: distance between two points
Thanks Nicos for your prompt response. Ok. so, in the point kinematics analysis, first I should define a point in the femur. then I repeat it for the tibia. and for the global frame, do you mean I should select global in the 'relative_to_body_name' section, for each point? And for the point distance...

distance between two points
Hi there, I want to measure the distance between two points. I tried to do it with Point Kinematic. but there is just one point to define with respect to a body name. how can it implement? For example, if we have a point in the femur and the other one in the tibia, how can we measure the distance ch...

Elastic foundation
Hello, I have some questions about the elastic foundation issue. - I know the formulation of the elastic foundation force. But in Opensim, I become a bit confused. I want to know that where is the references of contact forces? I mean how we can define the references of the contact forces? for exampl...

Re: problem in adding a ligament as 'acl' to the a model
The expected contents/format of the .osim file depends on the "OpenSimDocument Version" number at the top. For example, if the version number is greater than 40000, then I believe the PathPoints need a "socket_parent_frame" property that provides the full path to the parent frame. For example: <Pat...

Re: problem in adding a ligament as 'acl' to the a model
Thanks a lot for your help. I tried the structure codes witch you mentioned. It was helpful an worked. The new ligament add to my model. but there is problem the ligaments movement. I mean when I move the knee-angler-r (in the coordinate tab) the body will move without ligaments. I attached the Gif ...
