axle friction

[ziamele]

In a simulation with Algodoo of a pendulum I noticed that axle has internal friction that I cannot reduce and that in the long run causes the pendulum to stop even in the absence of friction with air and with agni other part of the system. Can anyone explain if it is possible to eliminate this friction?

Hi! Could you share a scene where this happens? Have you turned off air friction?
