如上圖所示，我設(shè)置的是兩個半徑不同的內(nèi)切圓柱面接觸。。設(shè)置是按 面跟面接觸

結(jié)果一步都算不了 直接  1U  2U 3U 4U 5U   提示不收斂，，警告如下

80 elements are distorted. Either the isoparametric angles are out of the suggested limits or the triangular or tetrahedral quality measure is bad. The elements have been identified in element set WarnElemDistorted.

There are 3 unconnected regions in the model.

Displacement increment for contact is too big.

麻煩各位給看下， 提點(diǎn)修改意見，初學(xué)者不勝感激?。?！
