I created manual connection points and double checked that they are properly connected at the troubled point. I have read that changing the detection method for contact elements from program controlled to Nodal-Normal to target. Also, reducing contact stiffness by changing the normal stiffness from program controlled to 0.2. I do not see where these settings are to change them though.
