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 and Run Model Advisor Checks.

Topics

Select and Run Model Advisor Checks

Use the Model Advisor to check a model or subsystem for conditions and configuration settings that you select, including conditions that cause inaccurate or inefficient simulation.

Address Model Check Results

After a Model Advisor analysis, you can highlight the results and fix check warnings.

Save Model Analysis Time

If you consistently run the same set of checks on your model, to save analysis time, use the Model Advisor dashboard.

Run Model Checks in Background

If you have Parallel Computing Toolbox™, you can run the Model Advisor in the background.

Save and View Model Advisor Reports

The Model Advisor generates an HTML report of the check results.

Model Advisor Limitations

When you use the Model Advisor to check your model, some limitations apply.
