Reply To: Force reaction for symmetrical and asymmetrical contact

[Stella Peloni]

Hello,

The difference in reaction forces when using symmetric versus asymmetric contact in simulations is due to the way contact and target are defined and how the rules for contact apply. In asymmetric behavior, one side is always contact and the other is always target. The rules for contact apply only to the contact side, meaning that the contact should not penetrate the target. The target is considered a geometric boundary that should not be violated by the contact. Results for the contacts are generated on both surfaces for symmetric while for asymmetric they are only generated on the contact surface.

You can, also, refer to this Forum post, which explains the difference.
