In a complex engine with 8 pistons, you can run Nipactivity (Hot) on all 8 simultaneously. CATIA will create a heat-map overlay showing which cylinder has the most dangerous thermal interference at full load.
Using MQL (Matrix Query Language), run:
list transaction where (id == 'Thread_942') select output;
This returns the exact command being sent to CATIA. nipactivity catia hot
Once you master basic nipactivity catia hot, you can apply it to advanced scenarios:
Before we tackle "Hot," we must understand the "NIP." In a complex engine with 8 pistons, you
The Scenario: A large aerospace supplier upgraded to 3DEXPERIENCE 2023x. Every Friday at 3 PM, the system would grind to a halt. The logs were flooded with: [ERROR] NIPActivity CATIA Hot - Timeout after 1800s.
Diagnosis:
The Fix:
Result: NIPActivity returned to "Warm" status. Fridays were no longer a crisis. This returns the exact command being sent to CATIA
