Thanks for the help Ayman. I will file the bug.

<t>Hi,<br/> <br/> While performing inverse dynamics analysis when I define the external load and run the analysis the software crashes. However, when the same model is run using the external force set xml file written using the above definition of load, the analysis runs fine. Is there any bug of su...

Hi Ayman,

The color code used for the body axis is different from that of the global axis. Could you please clarify which color (Red, Yellow and Green) stands for which axis (X, Y and Z).

Thanks.

Thanks for the help Marc.

<t>Hi Marc,<br/> <br/> I too thought the same. However, it comes out that the axes color codes are also not the same. The global axes have RGB color code whereas the body fixed axes have RGY color code. So, did you consider Y color axis as B, because if it stands for a different axis then the whole ...

<t>Hi Marc,<br/> <br/> While updating the model for inertia and mass center properties how did you understand the axes orientation of the body. The GUI doesn't explicitly mention the X,Y and Z axis on the coordinate frame attached with the body. Also, the center of mass is not graphically displayed ...

Thanks Marc. It was really helpful.

Hi Ayman,

Is there any model offered by OpenSim team that has all the data (including the human upper limbs) available in it?

Thanks.

<t>Hi,<br/> <br/> The Upper Extremity Model available for download has no mass, inertia and mass center data which is needed for Inverse Dynamics analysis. From where are the users expected to collect all the data for the bodies. The model has so many small bodies that obtaining the data seems virtu...
