Ok, thank you. I will try to define proper material properties.

Yes, I always recieve a warning of aprupt contact changes. 

"Contact element 569863 (real ID 15) status changes abruptly from no-contact -> contact (with target element 540864)." 

"Contact element 684247 (real ID 34) status changes abruptly from contact (with target element 685459) -> no-contact."
