Hello, I am trying to modify model Arm26 elbow axis into unfixed one. But i met 2 problems: 1. the rotation axes of joint elbow are (0.04940001 0.03660001 0.99810825), (0 1 0), (0.99810825 0 -0.04940001), respectively. But the first two axes are not orthogonal, is this ok? 2. i try to add the code a...

Thx very much!

Hello, i am a starter in OpenSim. i am working right now to modify the elbow part of the Arm26 model. My prof asked to change the elbow flexion axis from a fixed one to an unfixed one. Which means, when the arm slowly flexion and extension, the forearm rotates around an axis at distal humerus and th...

Hello Stanev and Curreli, i saw the discussion between you two and it trully inspires me a lot. Right now i am working on modifying an elbow model arm26, which was shared on the website of opensim. My aim is to change the elbow flexion axis from a fixed one to an unfixed one when the arm does flexio...

Hello, I met kind of similiar questions. I am a starter in OpenSim and i try to modify the arm26 model in my bachelor thesis. I mean in the original model, when the forearm does flexion movement, the axis in the elbow is fixed. Right now i want to modify it into unfixed axis when the arm does flexio...

Hello everyone, Does somebody have the experience of build a .osim model only by text editor like Notepad++? I have tried to use OpenSim for two months, and i get stuck right now. I mean, without graphical modeling, i have to know every coordinate of every point on the bones and muscles. How can we ...

Hello what is the difference between the file, for example, r_scaph.vtp and arm_r_scaphoid.vtp? i try to import both of these files, and it seems to me that scaphoid in these two files are just different size and different location. For that case, how can i get the precise location of these bones an...

i am using OpenSim 3.3 and try to add path of opensim in matlab, using the file 'configureOpenSim' to configure the environment but shows like following: what can i do for next?
