Does BushingForce have bug?

<t>Hi,<br/> I am not sure if this is a bug or not.<br/> This is my OSIM file to define a BushingForce in Arm26.osim <br/> .<br/> .<br/> <BushingForce name = "DirectionY"><br/> <isDisabled> False </isDisabled><br/> <body_1> ground </body_1><br/> <body_2> r_ulna_radius_hand </body_2><br/> <location_bo...

Ground contact model

<r>HI all,<br/> I want to use a set of spring/dampers to model foot/ground contact in a forward dynamic simulation. I found out that there are different linear and non-linear springs available.<br/> <URL url="https://simtk.org/api_docs/opensim/api_docs20b/">https://simtk.org/api_docs/opensim/api_doc...

Torque actuator xml code

<t>Hi everyone,<br/> I have some questions on torque actuator's xml script. <br/> 1- what does "-1.#INF" mean in min_control? can I replace it simply by -1?<br/> 2- What does "optimal_force" mean? Is it the maximum torque that the actuator can apply? Is it a force or a torque? and why is it OPTIMAL?...

How to add new components in the osim file

<t>Hi all;<br/> I was trying to find a document that explains how to add different available components to a *.osim file. say I want to add a spring, a damper, a force,etc.<br/> According to doxyjen documents, I know they are available, but how can I add them to the OSIM file?<br/> Cheers,<br/> Sina...

RE: Turn off printing results on cmd screen

<t>Hi Ayman<br/> Unfortunately it seems that it is not possible to redirect it from matlab. I will send a feature request,<br/> The problem is not clutter on the screen, but the time. For my specific forward dynamic problem, if I could turn off the screen display, I would save 20% of total time. For...

Turn off printing results on cmd screen

<r>Hi all,<br/> I am using the "forward dynamic" tool to solve a "dynamic optimization" problem using MATLAB optimization toolbox.<br/> As it's a dynamic optimization, it has lots of forward integrations and for each of them, the forward dynamic tool prints lots of data on cmd screen (An example of ...

Passive Joint Torque

<t>Hi all,<br/> I would like to add passive joint torques to my model to prevent unusual joint angles during forward dynamics. <br/> I can add the passive torque in older versions (like 2.0.2) but version 2.2 does not recognize the passive torque!! Is it deleted in new versions? If yes, why?<br/> Ch...
