Hello OpenSIM-Team, I would be very happy, for any help concerning RRA setups with point actuators in the feet (instead of the pelvis). Please find some plots, source files and the 3 sets of GRF setup files attached... I only got vertical ground reaction forces and the COP location for both legs. Fx...

Hello James, it works! Thank you very, very much for pointing me on this! Bit by bit, I replaced the Schutte specific properties with the Thelen default values. For most muscles this seem to work fine, leaving . Two muscles (at the wrist) don't work at all, Opensim wouldn't even load the model with ...

Hello James, thank you very, very much for looking into it. That's a very big help already! :-) The model I used consists of Schutte1993 muscles exclusively, instead of thelen2003 that you had been using. It seems like this might be the point. I tested to use my model with the motion, the actuator f...

Hello Opensim-Team, what I'm requesting your ideas and help about, is the following: For a bunch of excercises (e.g. biceps curl, shoulder abduction, ...) with different subjects and different loads. I like to simulate the muscle forces (SO) and moments (ID), using the Upper Extremity Dynamic Model ...

Hey there, I like to run Static Optimization from within Python using the Python Wrapper. Thus I create an analyzeTool from a template setupXML file and then fill in the specific values e.g. for the coordinate file to use. > analyzeTool = opensim.AnalyzeTool(setupXMLFile) ... > analyzeTool.run() The...

Hallo Patrick,
thank you very much for your help and sorry for the late reply! Referencing the geometry folder coming with the ULB model - which the MoBL Upper Limb Model that I'm using is derrived from - solved the visibility problem.

Thank you!
Stefanie

And here is another image to demonstrate the problem:
Original ulb model (left) and scaled to defaults (1.3 for right arm and 1.0 for the rest of the body) (right)

Thank you very much for your help!

And here is the output in the messages window, when performing the scale step with the above indicated scale setup file

Hello there, whenever I try to compute the scaling for the ulb fullbody model in OpenSIM 3.3 (scale file attached), the model gets distorted. E.g. the thorax is displaced in y-Direction and the joints and bodies get sheared and stretched (view image attached). I try to scale only the right arm, leav...

Thank you very much! It works!
