Yes, the file sent is using the old isDynamic, I knew it was just a quick hack (to test Chiara's script).
The logic is in line with #10, and the advantage of less operations still holds (same result could be obtained by replacing isDynamic by DOF_ALL in the diff).

Status in Yet Another Dynamic Engine: Confirmed

Bug description:
Does isDynamic means that Newton's laws skip the body? Or that forces don't contribute to its velocity? Various Translation/RotationEngines rely by convention on that Newton's laws skip the body completely.

There was a discussion on that topic http://thread.gmane.org/gmane.science.physics.yade.devel/1059 and we should draw conclusions now.
