Hello. I was wondering is there any way to have two axes location for a joint axis?
For example i need to rotate a joint from 0 to 10 around an axis and from -10 to 0 on another axis. Is there any possible way?

Hello. I need to change axis location of a joint. For example i am working on gait2392-simbody model and I need to change the location of knee axis for adduction.Could you help me?

Thank you so much for your help

Hello. I am trying to use Dr.Hang xu model. The "ModelwithKneeLigaments" model. I can not measure the ligament forces and applying ligament force to the bodies. How can i find that?!

Thank You

Hello. I used gait2392_simbody model and gave a specified motion and activation to the knee joint and muscles. I need to have total amount of torque on knee joint.How can I find it?!

Hello. I was trying to do some experiments on wrist model. But i found out that the skeleton parts doesn't have mass. (You can see 0 as mass property in model code).Doesn't it make any problem for estimating muscle forces while doing experiments?!

I know the main program code is in C++.But i was trying to make changes in Tug_of_War model and it doesn't need any programs. I made many other changes in different code without using C++ and reconstruction and it was ok. But once I tried to make changes in a main code and reconstruct the opensim pr...

Thank you dear Dr Millard for responding. Unfortunately you are explaining too professional and I can't understand all the details. Am i suppose to reconstruct the whole Opnesim program?! Am i suppose to change the details in main constructor codes (such as FiberForceLengthCurve code) and construct ...

Hello.I am trying to change passive fiber force-length curve properties in millard model.But it isn't possible to change some of its parameters in the program.I tried to change this parameters in the model script.But there is a problem whenever you try to open the model.There is the message: Excepti...

Hello.Does opensim muscles have mass in opensim?How can i find the value?
