[求助] 求助simufact welding中错误代码9992,具体的解决办法

求助simufact welding中错误代码9992,具体的解决办法。求告知详细的解决措施。降低负荷增量指的是什么负荷?请问跟网格质量有关系吗?
Error in 3D contact code. This is usually related to excessive iterative displacements, which cause difficulties in finding
the correct new position of nodes in contact. Possible remedies are:
- use the iterative penetration checking procedure;
- reduce the load incrementation;
- define the maximum change in the incremental displacement to
  be equal to e.g. a characteristic element length;
- for incompressible materials, only use the tensile stresses
  in the geometric stiffness matrix.
