我进行cncheck的情况如下: *** NOTE *** CP = 27655.984 TIME= 13:27:16
Deformable-deformable contact pair identified by real constant set 3
and contact element type 3 has been set up.
Contact algorithm: Augmented Lagrange method
Contact detection at: Gauss integration point
Contact stiffness factor FKN 0.10000
The resulting contact stiffness 0.79811
Penetration tolerance factor FTOLN 0.10000
The resulting penetration tolerance 0.53151
Max. initial friction coefficient MU 0.11500
Default tangent stiffness factor FKT 1.0000
Default elastic slip factor SLTOL 0.10000E-01
The resulting elastic slip 0.46464E-01
Update contact stiffness at each iteration
Max. friction stress TAUMAX 0.10000E+21
Average contact surface length 4.6464
Average contact pair depth 5.3151
Default pinball region factor PINB 2.0000
The resulting pinball region 10.630
*** NOTE *** CP = 27655.984 TIME= 13:27:16
One of the contact searching regions contains at least 107 target
elements. You may reduce the pinball radius.
*WARNING*: Initial penetration is included.
*** NOTE *** CP = 27655.984 TIME= 13:27:16
Max. Initial penetration 1.193559109E-02 was detected between contact
element 20738 and target element 20708.
You may move entire target surface by : x= 8.320933354E-04, y=
1.178083727E-02, z= 1.725638592E-03,to reduce initial penetration.
****************************************
1 CONTACT PAIR IS SELECTED
CONTACT PAIR HAVING REAL ID = 3 IS INITIALLY CLOSED
两个警告说到了reduce the pinball radius 和移动整个目标面按照所给出的位移, move entire target surface by : x= 8.320933354E-04, y=
1.178083727E-02, z= 1.725638592E-03,to reduce initial penetration.请问具体该如何操作,谢谢,我算的模型有几个警告,并且不收敛,望高手指点 |
