登錄若直接設通用接觸,一開始就不收斂(有Displacement increment for contact is too big.的警告信息);若使用面面接觸,同樣不收斂(Displacement increment for contact is too big.);若使用面面接觸,并設置調整過盈,則開始計算時會直接將上板向上調整9mm至與模具接觸。
Too many attempts made for this increment。(這個是報錯程序)下面的是出現的警告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. ”查找節點ID號后發現有幾個是彈簧選擇的面上的節點
