It turns out that essentially carpet-pulling OpenSim and overwriting the out.log file results in thousands of NULL values the next time the file is read (duh! :lol:). Due to this, upon completion of the first simulation, I make a copy of the log file for the next iteration. OpenSim then writes to th...

As an update - I have mostly figured out the first question. After checking for the warning in the out.log file, even though the file is technically open and can't be deleted, I'm able to open the file using `fopen()`, clear the file, and then close the handle: % Check for Simulation Warning outputC...

I am using Matlab 2015b to interface to OpenSim 3.2 and run a series of static optimizations. The script runs just fine and is working as expected; however, I would like to improve how I check whether an optimization was successful. After an optimization is run, I load and check the `out.log` file f...

And just like that, my problem has been fixed! Thank you very much for your input, Thomas, it's greatly appreciated

I am attempting to apply an ExternalForce to an OpenSim model during Static Optimization. I am currently using the arm26.osim model as a simplified starting point. The end goal is to use this knowledge to aid in performing isometric force production simulations. I am using OpenSim 3.2 and Matlab R20...
