求助：诚邀大家讨论abaqus钢结构节点的模拟问题

taixiangyin

大家好，我是初学abaqus，在模拟高温下钢结构节点时遇到了诸多问题。下面是我提交的时候出现的error，请大家指点一下怎样修改，谢谢
1. the elements contained in element set ErrEleExcessDistortion-step1 have distored excessively.
2. for a contact surface, the facets of the elements in element set ErrElemfacetCoin3d-Step1 have coincident nodes. the mesh must defined so that surfaces do not have coincident nodes (sometimes the redundant nodes can simply be removed from the mesh by equivalencing in the preprocessor).

kkkttt

1. 变形过大，单元过度扭曲
2. 应该是接触定义有问题
