Akshay,

Thank you for your response. I made the Newton-Raphson residual plots and surprisingly it showed that the problem is not at the straps. The problem is at one of the inner membrane and outer membrane connection points. 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. Do you know where they are located or of any other solutions?

Thanks,

Brian
