Hi Hugo, thank you for your response(s)! I tried the following, but am still not getting collisions:

– reducing the vertex count of the collision meshes
– reducing the time step
– increasing the contact/alarm distance

My gut feeling is the AnatomyModelling example application is written for an older style of SOFA programming. I’m now trying to build up a less complex scene with the features I need.

Jason and I have been working together on this model. An update: adding a DefaultContactManager (with response=’distanceLMConstraint’) and a DefaultCollisionGroupManager on the root node, and then EulerImplicit / CGLinearSolver / LMConstraintSolver solvers on the muscle node, seems to have helped. The muscle does still interpenetrate the bones, but I think it is colliding some of the time.

Two questions:
1) What do we need to tune to get better collision detection?

2) What does the DefaultCollisionGroupManager do, and do we need to tell it which objects should be colliding?
