Rolling On Surface Constraint

[Aspen Taylor]

Good evening!

I am currently trying to use the RollingOnSurfaceConstraint in OpenSim to help constrain the feet of my model. After coding the constraint in XML, the model will not open in OpenSim. I coded the constraint as <RollingOnSurfaceConstraint>. Any advice on this topic would be much appreciated!

Thank you!

Best,
Aspen

Hard to debug with the info given. It's usually very easy to miss closing tags (e.g., </RollingOnSurfaceConstraint>) so that would be the first place to look. If you need a place to copy the correct XML tags, check out the option in the GUI: "Help --> XML Browser" to make sure you have the right tags.

Thank you for your advice! I checked out the tags and double checked to make sure they were all correct. However, the model still does not open. I attached an image of the code below.

Is anything displayed in the Messages window? Someone might be able to help you investigate if you post a MWE (https://en.wikipedia.org/wiki/Minimal_working_example).

Nothing pops up in the navigator or messages windows. I do not get any pop up windows. I attached the model below with the RollingOnSurfaceConstraint.
