This physics engine works with penetration detection of any object. If a penetration (intersection) is detected the simulation will run backwards and forwards in frame-time, untill a accurate collision time is found. After that, the last detected collision is resolved.

More features:
ConvexPolygons as Springmodels
Time-exact simulation resolve
Space-Subvision by grids

I'm actually stale on proper terminology, but do you have an efficiency metric for your simulation? In other words, how close to real time could you get for a bouncing ball on a surface or something like that?

I did a lot of research on gear trains a few years back, and worked with a colleague where I laid out the physics of contact between gear teeth while he coded up the actual contact algorithm. I know he researched many different algorithms before picking one, but we never got anywhere close to running in real time.
