Run Model Checks

Check that model simulates accurately and efficiently

The Model Advisor checks a model or subsystem for conditions and configuration settings that can result in inaccurate or inefficient simulation. You can specify the conditions and settings to check. See Select Checks and Run Model Advisor.

Functions
