Hi,

I am doing a static simulation on a assembly. It is a timing belt with a cleat and this cleat carries the load.

As you can see in the first image, do the cleats not touch the belt in the marked area. But after creating a mesh and running the load, this two pieces connect (on the other side as well).

In the second image you can see they connect. Especially in the bottom you can see this piece is really pulling the belt. (shown is the stress plot, but it also happens at the deformation plot).

Can someone help me to prevent this?

Could it be that the mesh-size is too coarse? So that the mesh size is larger than the distance between the to surfaces (d=0.5mm)
