若直接設(shè)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(shè)置調(diào)整過盈，則開始計(jì)算時(shí)會(huì)直接將上板向上調(diào)整9mm至與模具接觸。

Too many attempts made for this increment。（這個(gè)是報(bào)錯(cuò)程序）下面的是出現(xiàn)的警告Displacement increment for contact is too big.

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(jié)點(diǎn)ID號(hào)后發(fā)現(xiàn)有幾個(gè)是彈簧選擇的面上的節(jié)點(diǎn)
