ansys合并节点后提示警告？

zxyg.txt

在使用合并节点后，出现这样的警告：After NUMMRG,NODE, node 559 (and possibly others) is associated with more than one solid model entity.  Future commands which depend on the node to solid model connectivity (meshing, mesh clearing, solid boundary condition transfer, etc.) may not operate properly. NUMMRG,KP may correct this problem.  忽略施加重力，施加约束求解，提示约束不够，不收敛。之后按照提示在合并节点前先合并关键点，施加工况计算，还是不收敛，请问现在应该怎么办呢？
