如上图所示，我设置的是两个半径不同的内切圆柱面接触。。设置是按 面跟面接触

结果一步都算不了 直接  1U  2U 3U 4U 5U   提示不收敛，，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.

麻烦各位给看下， 提点修改意见，初学者不胜感激！！！
