Look at the behavior of my suspension, is it normal? They do 1 000 000 N with 5 of damping and they jump like if I had 0.1 of damping, for only 300Kg.

I don't know if it's my computer but the spring often bug. They have a lot of problem, they make algodoo reboot, springs have a strange behavior, sometimes I can't use them, they don't want to be created ...

It's the same on yours?

Yes, it is normal for such unrealistic values and 60Hz sim freq, but even with that you could fix it if by set "forceDirectSolve = true for springs.

Direct solve useful almost everywhere, but it use more CPU and need higher sim freq for fast-rotation hinges.

You could also try directConactSolveAll=true in console, that will remove geom penetration on high force.
