<t>Hi all,<br/> <br/> Quick question about the model Arm26, <br/> <br/> Does OpenSim take into account the gravity, in a way that would permit the arm to "fall" during an extension? (by "fall" I mean, that extensions are nearly effortless compared to flexions, therefore, triceps activations should b...

<r>Hello,<br/> <br/> I'm trying to run the static optimization using arm26.<br/> <br/> I modified the limits of flexion (from [0..130] to [0..170]) by editing the .osim file.<br/> But I noticed that when the flexion angle of the elbow gets over 145°, the static optimization tool fails either we're u...

<t>Hi Ayman,<br/> <br/> I used the model you specified above.<br/> <br/> We faced a problem with the inverse dynamics tool that we resolved by modifying the mass and inertial values of the bodies.<br/> Then, when we tried to use the static optimization tool, the optimization failed, with the followi...

<t>Hello,<br/> <br/> I would like to compare OpenSim results (muscle activation) to phisiological results (measured activations). <br/> <br/> I'm using Arm26.osim and I had some results that seemed a bit weird: some muscles activations where too high (~0.8) for a long time, while the movement was so...

Ok, thank you Anders.

I tried your first suggestion, it worked.
I'm trying to use the other tool now because it seems quite interesting.

<t>Hello,<br/> <br/> I want to compare the trajectories of the experimental markers and the virtual ones, But I don't find the virtual markers data (the data saved in the motion file after doing the inverse kinematiks task does contain the experimental markers data).<br/> Can anyone please tell me w...

Hi Ayman,

Thank you, it worked after I edited the .osim file(unclamping doesn't work, it was unlamped from the beginning).

<t>I got the same error when I started working on the developers guide, I replaced "RegSvr32" with the generated binary and it was fine then.<br/> <br/> Did you try to run the binairies generated by the code in the build folder you specified (to make sure that there's something wrong with the binari...

Thank you Ayman for the explanation.
