soft body internals

I'm currently looking into Bullets Soft Body abilities. Since documentation as to what these abilities are exactly seems to be scarce i will try my luck here in the forum.

These are the questions i couldn't figure out yet:

1. What deformation model/algorithm is used for volumetric Bullet Soft Bodies? I.e. how are the vertices of the collision shape and/or visual model deformed? Either i was scanning the code too superficially or i was looking in the wrong place.

2. I can't quite make out if for example the "Softbody Volume" demo does some kind of volume preservation.
Can Bullet Soft Bodies be roughly volume preserving?

3. The "Softbodie Init Cut" demo seems to do some kind of punching. Is it possible to tear or cut volumetric Bullet Soft Bodies?

Any help or hint is greatly appreciated.

Thanks,
Martin
