定义了接触咋老是出错!
计算一个边坡,按平面应变计算,需要定义挡土墙和土坡的接触,计算时老是出现如下错误:*** WARNING NO. A3 ***
Contact group 1 has 16 initially penetrating contactor nodes
Maximum penetration: 0.1000000E+01
NOTE:
Nodes can be initially in contact either by design or due to finite element discretization or due to a model overrideing error. Therefore, please check the contact surface definitions (especially in the case of a gross overlap). Also check the orientation of all contact surfaces (especially the target surfaces).
不知怎么改正,请各位大侠指教! 你这个初始穿透量太大了,应该考虑重新划分网格。 2# wild_field
土和墙的接触面我用两条重合的直线,墙面是目标面,两个面得划分密度不一样,用六节点三角形单元划分网格,
您说重新划分网格,但是不知道怎么去改,出现这种问题是由于网格划分不合适还是其他原因?搞不明白,请多多指教 初始穿透量大不是原始几何的原因,就是划分网格促成。
设置接触组时,可以试下初始穿透选项选择ignore。 4# wild_field
好的,我试一下,多谢!
