@mindsweeper,

Turn the air resistance off this time and the behavior seems to turn somewhat back to normal.

Yes, exactly my point, that should prove the unpredictability of WM2D imho..

Here are another two, I cannot remember who posted the first one but Stefan posted the second one. Both are WM2D stuff ups.

@ Omnibus

I know if you change almost any parameter it behaves almost normally. This is hardly the point though. If the system gives false results on a pure setting (ie. no outside influences) it will hardly give more reliable results when outside forces enter into the picture. Are you seriously suggesting that the model in question will work as shown in a vacuum?

Take a look at the calculated and displayed velocity and acceleration. There's something very confusing about all this. Someone should explain what's going on. Otherwise it's just a waste of time to model these contraptions. (see attached)

Correct. That was exactly my point. If you go back some 10-15 pages you'll see that I raised exactly this question about the device working in vacuum. The explanation given was that elements such as springs are not ideal and there are always some losses which in this case are modeled by the air resistance (and I thought I read somewhere in several other ways such as deliberate inducing slight back force, back torque and the like).

The problem is that in this last example (before the two you gave) the "correct" result appear to be when air resistance is turned off rather than on. Go figure.
