I would like to know if the OpenSim not accept an open-surface to define a contact geometry.
I tried to add a close-surface geometry and I could perform a force report analysis. However, when I added an open-surface (as flat mesh), I got the following error message: "unknown exception".
How can I solve this problem.
Thanks for your help.

RE: Contact Geometry
Hi Margarida,
I ran into similar issues when my meshes weren't water tight. Why do you need a a flat 2d mesh? Why not take the geometry and extrude it a little so that it is a watertight, 3d model?

RE: Contact Geometry
Hi Margarida,
The collision detection algorithm in-use in OpenSim works only with closed surfaces (basically to resolve the issue of what's inside/outside). Sorry if that was not documented properly (the message/error wasn't descriptive. Please file a bug report for that), but you can extrude a plane to give it some thickness and that should do it.
Good luck,
