Link — Nipactivity Catia Hot

CATIA is the gold standard for high-stakes engineering where "hot" systems and complex "activities" must be precisely managed:

Rarely used, but powerful: tells you the minimum gap required to prevent "hot" nip. You iterate a tolerance, and CATIA tells you the safety margin. nipactivity catia hot

A "hot" NIP region is not a warning—it’s information. It simply tells you where the solver is working hardest. The real issue is uneven activity (e.g., 90% of NIPs in one corner). That indicates poor mesh quality or unrealistic boundary conditions. CATIA is the gold standard for high-stakes engineering
