Convergence Problem with Tendon-Pulley System

Convergence Problem with Tendon-Pulley System

Convergence Problem with Tendon-Pulley System

(OP)
Hi,

I am trying to run a static calculation where I apply a pressure (19MPa) at the tip of a tendon, that is in contact with finger pulleys (represent here as cylinders).

The contacts are "Node to surface contacts" with penalty method.
The calculation is not converging and the error message is : Time increment is less than minimum specified.

I also have warning as seen below :

27 nodes may have incorrect normal definitions. The nodes have been identified in node set WarnNodeIncorrectNormal.
