请问节点模拟开始不收敛，出现下列警告是何原因，应该怎么调整呢？ 20

The ratio of the maximum incremental adjustment to the average characteristic length is 4.77436e-02 at node 3317 instance gangtong-1 on the surface pair (assembly_s_surf-60,assembly_m_surf-60).

Not all the nodes that have been adjusted were printed. Specify *preprint,contact=yes for complete printout.

Displacement increment for contact is too big.

Displacement increment for contact is too big.

Displacement increment for contact is too big.

The strain increment has exceeded fifty times the strain to cause first yield at 73900 points

The strain increment is so large that the program will not attempt the plasticity calculation at 73898 points

The plasticity/creep/connector friction algorithm did not converge at 2 points
