Hello Abaqus users,
I guess i need a trick to complete the model since 99% of the job was already done, I got many warning messages such as:
solver problem. Zero pivot when processing D.O.F. 3 of 1 nodes. The nodes have been identified in node set WarnNodeSolvProbZeroPiv_3_2_653_1_1.
Excessive distortion at a total of 259 integration points in solid (continuum) elements
Displacement increment for contact is too big.
Displacement increment for contact is too big.
Displacement increment for contact is too big.
Displacement increment for contact is too big.
Displacement increment for contact is too big.
Displacement increment for contact is too big.
Displacement increment for contact is too big.
the material behavior used is concreted damage plasticity, and the static general step was adopted.
I used contact control and analysis = discontinuous to overcome the premature divergence. Is there any trick or any thing else that can help.
Your idea is highly appreciated.
Thanks
