登录若直接设通用接触,一开始就不收敛(有Displacement increment for contact is too big.的警告信息);若使用面面接触,同样不收敛(Displacement increment for contact is too big.);若使用面面接触,并设置调整过盈,则开始计算时会直接将上板向上调整9mm至与模具接触。
Too many attempts made for this increment。(这个是报错程序)下面的是出现的警告Displacement increment for contact is too big.

FOR P=0.0 0.100 CONTACT FORCE ERROR TOLERANCE FOR CONVERT SDI=YES 1.00 DISPLACEMENT COMPATIBILITY TOLERANCE FOR DCOUP ELEMENTS 1.000E-05

It is likely that either a displacement boundary condition has been applied directly onto a constraint equation or two or more constraint equations share too many degrees of freedom. ”查找节点ID号后发现有几个是弹簧选择的面上的节点
