模态分析

模态分析的时候，出现了这个问题：The detected initial penetration/gap is relatively large for certain contact pairs. This may produce inaccurate results for Bonded and No Separation contacts using formulation other than MPC. This large penetration/gap can be identified by generating the initial contact results.

我更改了接触设置还是不行，请问这是为什么呀，需要怎么更改？
