Known Bugs

1.Units in Dynamics Graph -

Corrected 17-1-142

2. Negative Inertia

If the Power Source is aT a “Floating Joint” in a kinematic-chain, e.g. at the end of the Crank or Rocker in a 4-bar Crank-Rocker mechanism, it is possible that the Inertia Coefficients (in Inertia FB) are negative - which does not make sense!

The Dynamics model cannot run.

Solution - you must make sure the Power Source is a “2D-Cam” or a “Grounded Joint”.
