OpenSim crashing issues

Post by Katerina Blazek » Thu Apr 17, 2008 7:46 pm

OpenSim's been crashing quite frequently while in the middle of CMC during the following:

- while simulating slow walking if I run my own CMC settings file, using the various parameters that May sent out. I should mention, though, that in the settings file that OpenSim generates for me, there are no objects in the AnalysisSet, so there are settings I can't do anything about. If I run May's CMC settings file directly, everything works.

- while simulating running, even if I run May's settings file directly, OpenSim will crash after going through about 2 seconds' worth of simulation. Everything looks fine just before the crash.

A typical error message is below: anyone have any advice?

Thanks!
Katerina

Hi Katerina,
Sorry to hear about the problems. It sounds like CMC runs fine for walking, with the files I sent. But it crashes for running, with the files I sent.

It also sounds like it crashes for walking when you try to run it using the CMC tool (not the files I sent). Which crash causes the error message you included (walking or running)?

Does RRA finish ok for the running data?

Hi Katerina,

So I was having problems with RRA, and then I remembered that in the IK solution from last week, I did not have the subtalar and mtp joints locked. Did you check this? If not, that may help.

To lock these joints open the model file (*.osim) in a text editor and search for the section the looks like the code below. Then make sure the "locked" tag is true for left & right subtalar and mtp angles. Then re-do IK and RRA. Hope this helps!

<SimbodyCoordinate name="subtalar_angle_r">
<default_value> 0.00 </default_value>
<initial_value> 0.00 </initial_value>
<tolerance> 0.00000001 </tolerance>
<stiffness> 0.00 </stiffness>
<range> -1.57079633 1.57079633 </range>
<keys> a_key </keys>
<clamped> true </clamped>
<locked> true </locked>
<restraint_function/>
<min_restraint_function/>
<max_restraint_function/>
<restraint_active> false </restraint_active>
<constraint_function/>
</SimbodyCoordinate>

(Good observation, Sam!) Yes, definitely lock the subtalar and mtp joints. For the slow walking example we did in class, I think that the motion in these joints was small enough that it was ok to lock them *after* inverse kinematics.

But I bet the motions were much larger after inverse kinematics for running. So, yes, lock them *before* running IK and see if that helps.

In general, you want to decide on which model dof to lock before even scaling, but I think we overlooked this in class. So sorry for the problems.

Katerina and all,

The GUI is supposed to create a settings (*_setup.xml) file. After that it's the exact same code executing either from the command line or the GUI. So, I'd like to separate the issues/crashes as either "GUI issues" if the file we end up with is bad (these are easy to reproduce and fix) or "CMC issues" which are much harder to reproduce and to fix as they may happen midway through CMC after minutes or hours for various reasons (including locking the joints or that the model is not strong enough to reproduce the motion, ..etc.).

The questions for Katerina:
1. Does slow walking work from the GUI?
a) using May's file.
b) using a file created entirely in the GUI.
2. Same question as 1. but for running.

Thanks for your help tracking these issues and for making OpenSim better for future users.

Best regards,
-Ayman

Hi Ayman and everyone else,

to clarify:

Slow walking RRA and CMC work for me when running them with May's setup file for the whole of the movement (when we have GRF's); RRA is fine with a setup file created by the GUI, but CMC crashes at the first timestep if I run it with a setup file created only by the GUI (but with the same settings as May's file).

For slow running, RRA will run for the whole movement using May's setup file, but CMC crashes halfway through. RRA from a GUI setup file will also run for the whole movement, but CMC crashes as well.

I'm going to try running OpenSim from the command line and see if I can figure out what's wrong.

Thanks!
Katerina

Katerina,
Thanks for the clarification.

You might also try to do the following for your running trial: Run CMC, and as it runs, keep an eye on the times in the message window. Try to note the time when it crashes. Then change your final time in the CMC setup file to some time *just* before the crash. It ought to run just fine for that shorter duration. Take a look at the output files. Was it tracking the kinematics well until the crash, or did it look like there were large errors? Were the residual or reserve actuators maxing out at any time--if so, increase the min/max allowed for those actuators and see if it still happens.

May and all,

I believe I got to the real bottom of the "space in the path" problem. The problem is specific to the list of files for Actuators. Since the list is written to the XML file space separated under the XML tag <actuator_set_files>, whenever a file has a space in the path e.g.
"C:/Program Files/OpenSim/actuators.xml"
It gets interpretted as 2 files
"C:/Program"
"Files/OpenSim/actuators.xml"
and that causes the crash downstream.
The workaround for now is to replace the filenames under this tag <actuator_set_files> to use relative path and make sure it does not have spaces in it. You can verify you got the right files by opening the CMC or Forward tool dialog and going to the "Actuators and External loads" and edit the list of Actuator files.

Hope this helps,
-Ayman

Hope that
