请教各位,我在做车架静力分析的时候发现应力太大,位移也快要有三米了(单位没有问题) 求解报错:"smallest negative equation solver pivot term encountered at UX dof of node 13956.check for an insufficiently constrained model"我采用的是全约束
"selected volumes attached to area 1378 are not meshed.surface load pres on this area is not transfered"所有的面我都划分网格了,我真的搞不明白了.请各位帮帮我.
