*** NOTE *** CP = 742.922 TIME= 12:03:28
Symmetric Deformable- deformable contact pair identified by real
constant set 23 and contact element type 22 has been set up. The
companion pair has real constant set ID 22. Both pairs should have
the same behavior.
ANSYS will keep the current pair and deactivate its companion pair,
resulting in asymmetric contact.
Contact algorithm: Augmented Lagrange method
Contact detection at: Gauss integration point
Contact stiffness factor FKN 10.000
The resulting initial contact stiffness 0.14457E+06
Default penetration tolerance factor FTOLN 0.10000
The resulting penetration tolerance 4.1502
Default opening contact stiffness OPSF will be used.
Default tangent stiffness factor FKT 1.0000
Default elastic slip factor SLTOL 0.50000E-02
The resulting elastic slip 0.27899
Update contact stiffness at each iteration
Default Max. friction stress TAUMAX 0.10000E+21
Average contact surface length 55.797
Average contact pair depth 41.502
Default pinball region factor PINB 0.50000
The resulting pinball region 20.751
*** NOTE *** CP = 742.922 TIME= 12:03:28
One of the contact searching regions contains at least 7814 target
elements. You may reduce the pinball radius.
Initial penetration/gap is excluded.
Bonded contact (always) is defined.
*** NOTE *** CP = 742.922 TIME= 12:03:28
Max. Initial penetration 160.848824 was detected between contact
element 1703168 and target element 716308.
You may move entire target surface by : x= 160.848824, y= 0, z= 0,to
reduce initial penetration.
*WARNING*: The detected penetration is larger than the pair based
pinball. Please verify the pinball radius carefully.
*WARNING*: The geometric gap/penetration may be too large. Increase
pinball radius if it is a true geometric gap/penetration. Decrease
pinball if it is a false one.
*WARNING*: The initial penetration/gap is relatively large. Bonded/no
separation option may cause an accuracy issue. Switch to MPC
algorithm or you may use the CNCHECK,ADJUST command to move the
contact nodes towards the target surface.

SUMMARY FOR CONTACT PAIR IDENTIFIED BY REAL CONSTANT SET 22
*** NOTE *** CP = 1020.969 TIME= 12:07:24
Contact pair is inactive.
*** NOTE *** CP = 1021.016 TIME= 12:07:24
One of the contact searching regions contains at least 384 target
elements. You may reduce the pinball radius (current value
20.7507507) for contact pair identified by real constant set 23 to
speed up contact searching.
