请教！

在模拟正挤压时遇到以下问题：
*** INFO: Begin of Simulation for Run# 1
Starting time is:Wed Mar 05 23:10:03
*** INFO: End of Simulation for Run# 1
FEM MESSAGE:
arning: Node 151 has conflict contacts
with Objs. 3 and 2
The second contact will be ignored.

Eqs. New Profile Ave. Bandwidth
10824 270548 48
Error : Conflict in normal directions of two contact surfaces
Object No = 1 Node No = 49
1st Contact Normal = -1.00000E+00 0.00000E+00 0.00000E+00
2nd Contact Normal = 1.00000E+00 0.00000E+00 0.00000E+00
Ending time is:Wed Mar 05 23:10:07
*** INFO: Simulation Module Indicates End of Simulation
*** INFO: End of Automatic Remeshing Run -- Bye###
Total Number of Runs = 1
选择的求解器：conjugate-gradient; 迭代：direct iteration
出现冲突的节点都在与凸模和凹模都接触的交线上。
请大家发表意见，谢谢！
