Hello, I have a question on the contact definition, I hope to win your guidance and support.

When defining the contact pairs in ANSYS workbench, do we have to guarantee there is only one element in contact, or we do not have to care how many elements involved in a contact? Like the following solver output, it reminds me there are 1047 elements in contact. Do I have to reduce the Pinball to reduce the number of elements in this contact pair?

 

 *************************************************

  SUMMARY FOR CONTACT PAIR IDENTIFIED BY REAL CONSTANT SET          24

 Max.  Penetration of -3.590422705E-15 has been detected between contact

 element 208388 and target element 208515.                              

 

 Max.  Geometrical gap of 5.133514676E-02 has been detected between     

 contact element 207658 and target element 208524.                      

 For total 2796 contact elements, there are 1047 elements are in        

 contact.                                                               

 Contacting area 18.6775108.                                            

 Max.  Pinball distance 0.2.                                            

 One of the contact searching regions contains at least 50 target       

 elements.                                                              

 Max.  Pressure/force -6.481163396E-09.                                 

 Max.  Normal stiffness 1557234.48.                                     

 Min.  Normal stiffness 1557234.48.
