Hello, I have a MATLAB code that runs successfully on a Windows desktop but fails with the following error on Ubuntu 20.04 system Java exception occurred: java.lang.RuntimeException: SimTK Exception thrown at Integrator.cpp:431: Integrator initialization failed apparently because: SimTK Exception th...

Hello, So I have used MATLAB code to make some modifications to the arm26 model. However, MATLAB crashes while calculating the length parameters of the fourth muscle. The code successfully calculates the length parameters of the first three muscles, however it crashes and exits without any error. Fu...

Hello, I have a MATLAB code that takes about 7-8 mins to run, with the following line taking more than 5 mins state = manager.integrate(timed); with timed = time(i+1)-time(i); I was looking for a way to speed up the integration process. Can we use any other method or function? Any help would be appr...

Hello Team, I wanted to simulate hypogravity using the full-body model by Rajagopal et al. Before going forward with it, I wanted to ask whether I need to change the value of gravitation in the model's .osim file and then implement hypogravity GRF data or just implement the hypogravity GRF data and ...

Thank you Carmichael and Thomas for your replies.
I will try your suggestion Thomas and would let you know how it goes.

Hello, I wanted to know if there is a way to add weightage to muscles before performing CMC, like the way we add weights for joints. I tried adding a task for the said muscles in the CMC task file with weights but the output generated did not show any effect of weights on the activation pattern of t...

Yes, that seems to work. Thank you Thomas.

Thank you Thomas. Will try your suggestion and revert.

Thanks Carmichael for your reply. I have already gone through this document. I want to set up muscle activations as x_nodes with values defined for each time frame. Here in the link, you have provided, the settings only talk about setting maximum and minimum values. Can you please help in suggesting...

Hi, I would like suggestions on how I can use EMG activation values and implement them as muscle controls to conduct a CMC simulation. I tried using EMG values as control constraints in the CMC for one muscle but it does not seem to work. How can I verify that the implementation is happening correct...
