Timing belt will "break" with a pretension of 3000 N

felixkonstantin.schymski
I´d like to create an AT10 timing belt. The geometric profile is no problem, neither the pulley set nor the creation of the belt (length 2000 mm). But I want to impact a pretension force of at least 3000 N on the belt. When I start a simulation with such a strong force, the belt starts to "break".
 
Are there some special settings I need to adapt, or is it simply not possible to impact such a strong pretension on an timing belt model?
 
Thanks for your help!

    I'm not familiar with how that belt model is setup.
    But your picture seems to show the non-symmetry of the Field element. You would expect some gaps in the geometry of the belt as the geometry solids themselves does not change shape, even though the flexible elements between them stretches out.
    I'm more worried about the angles I see of the connecting parts. When we developed the Tracked vehicle toolkit, we intentionally doubled all field elements so that for each connection there are two fields, going in opposite direction, each with half the stiffness and damping. In this way we could eliminate the non-symmetry.
