Hello All,
I am running a peel test analysis to determine the properties of cohesive elements. I have attached a file with the name "loads and BC" that shows the load applied and the BCs. I have given the interaction properties between the adherend (CNT) and adhesive (epoxy). I have given the material properties to the same. However, I get the following error message each time I run the analysis-
[highlight #CC0000]Solver problem. Zero pivot when processing D.O.F. 3 of 17 nodes. The nodes have been identified in node set WarnNodeSolvProbZeroPiv_3_1_1_1_1.
Solver problem. Zero pivot when processing D.O.F. 1 of 25 nodes. The nodes have been identified in node set WarnNodeSolvProbZeroPiv_1_1_1_1_1.
Solver problem. Zero pivot when processing D.O.F. 3 of 7 nodes. The nodes have been identified in node set WarnNodeSolvProbZeroPiv_3_1_1_1_1.

I have identified the nodes to be at the boundary condition. I am not sure as to how I can proceed further. Kindly help me. Thanks.
