Hi Lomas,
We have had this issue before and it was seen that it was a result of the graphics card. Make sure the performance settings are favored over quality.

If that doesnt work, try on another system with faster processing power and see if results improve.

Hi Cobus, Scaling can take some tweaking to get correct. There are some Video tutorials located at this link; http://simtk-confluence.stanford.edu:8080/display/OpenSim/Getting+Started+with+Scaling One way I get better results is to line up the scaled (but not moved) model against the collected marke...

Hey Nathan, Yep your right, I meant setModelFileName(). So the short of it is this- setModel() is an abstract tool that has a property of stripping the actuators and adding a bunch of controls. As I understand. In ID this doesnt matter because they aren't involved in the calculation of the dynamics....

Hi Nathan,

Been playing around with acouple of things with the setup. If i pass a file path rather than an object into setModel() It seems to run fine. Perhaps try that and get back to us.

Hi John, OpenSim doesnt have any inbuilt ability to do this. Most commonly, people use NMSbuilder (http://www.nmsphysiome.eu/). An example can found here: http://simtk-confluence.stanford.edu:8080/download/attachments/3376307/Demo+NMSBuilder.pdf?version=1&modificationDate=1346188065790 There are als...

Hi Corey, So this error is due to the way the muscle names are written in the files. OpenSim reads dots in a particular type of way. The outcome, in this case, is its cutting off everything before it and then looking for a muscle called "1-L3_r", which doesn't exist. You will have to go through the ...

Hi Guilia, If you can post an example of your .csv file and perhaps we can help? There are also range of available methods for converting data located here: http://simtk-confluence.stanford.edu:8080/display/OpenSim/Tools+for+Preparing+Motion+Data These are generally dealing with c3d files but you wo...

Virgil, OpenSIm comes with a models folder that contains both data and models. Tutorials, which can be run with these models and data, can be found here: http://simtk-confluence.stanford.edu:8080/display/OpenSim/Examples+and+Tutorials Additional models can be downloaded from the OpenSim project page...

Alex,
activation cannot be negative.

Hi Anne, Unfortunately there isnt much documentation around describing this. The reporter force is the net force of the contact between the two contact surfaces. It will report the 6 net force components (Fx, Fy, Fz, Mx, My, Mz). There currently is no way of accessing the individual forces between e...
