[ODE] Values required to produce at leastsemi-realisticfrictionusing the default constant-force-limit model?

[George Birbilis]

my feel is that a rolling sphere (with a torque at an axis passing through
the sphere center and parallel to the horizontal plane), won't move if
there's no friction with the ground. It will keep spinning at the same place
(unless it had some linear velocity too)
