RE: Customer toruqe

Hi Daniel,

Thanks a lot for the information. Do you know the approximate time when version 2.0 will be released? Just want to determine what to do next.

Thanks,

RE: Customer toruqe

<t>Good afternoon,<br/> <br/> My advisor helped me contact professor Delp, and here is what professor Delp said: It's possible to add a custom "actuator", but it's a bit of a pain because you would have to modify the source and re-compile the code. We are about to release OpenSim 2.0, which will mak...

RE: Cost function.

<t>Andrea,<br/> <br/> As far as I know, Opensim is also able to do forward simulation without existing experimental data. By changing muscle excitation pattern, you can predict the behavior of some certain patient. <br/> <br/> You can refer to the following paper to find more information: "OpenSim: ...

Customer toruqe

<t>Good afternoon,<br/> <br/> Does anyone know how to add an active torque to a joint? For example, adding a torque that is proportional to the joint angle (T = K*theta) to a joint. In other words, the profile of the torque is unknown, Opensim should be able to calculate the torque using the known s...

RE: squat/fall simulation

<t>Ajay,<br/> <br/> Thanks for your reply. It's pretty helpful.<br/> <br/> I did follow the tutorial 3, but the OpenSim always automatically closed without any warning when I did the inverse dynamics. I can't figure out the reason, so I switched to another computer, where it works very well.<br/> <b...

squat/fall simulation

<t>Good morning,<br/> <br/> First, thanks the Opensim group for your hard working. Opensim is a great one.<br/> <br/> I am just starting with openSim, so I have some rookie questions:<br/> Is it possible to do a squat/fall simulation in openSim and find torques about knee or is it possible to find h...
