Summary0000022: sixDoFRigidBodyMotion: Acceleration used as force
DescriptionIn updateForce(pointField, vectorField, scalar) the global acceleration is calculated (l.436). It is passed to updateForce(vector, vector, scalar) in l.442. This method uses it as a force (fGlobal, l.387). In l.397 it is again devided by mass_ to calculate the acceleration.

Well spotted. There was also a problem with the torque - it was being
transformed to body local coordinates twice too.

Luckily, the updateForce function on line 419 is never called by
anything.

Thanks for reporting, I've pushed a fix to 1.7.x.
