many Sliding Contacts in Sol101 Contact analysis


Dear users


I am doing a contact analysis using sol101 as shown in the figure I attached.


If you look at the calculation results, you will see 161568 NUMBER OF CONTACT ELEMENTS CREATED,


and 144772 sliding contacts. 


The number of sliding contacts seems to be too large, and it seems that the contact pressure is not even.

The offset of the inner cylinder is 0.5mm and the coefficient of friction is 0.2.


Any advice would be appreciated.
