Problem with Static Optimization

[Alessia Franceschi]

Hi,
I'm working with the MoBL_ARMS_Upper_Limb_Model_OpenSim and I've created a file.mot to reproduce the prono-supination motion. I want to know which muscles activate this motion and I'd like to use the Static Optimization tool but when I click to "run" everything disappear. OpenSim closes!
I can't read neither a message of error so I can't understand what is wrong. I've only the file.mot as input.
Do I have to create a file to specify the gravity as external load?

Thank you.

Hi Alessia,

There should be an ouptut message printed somewhere called 'err.txt' and 'out.txt'. These may be in your OpenSim home folder. The out.txt should have the last messages printed before the crash. See if you can find those and get back to us.

Cheers,
