Ansys Your Product License Has Numerical Problem Size Limits Verified [better] | Working

Seeing the text means your license is working exactly as intended. It is a signal that your current model fits within the bounds of your specific software tier, allowing you to proceed with your simulation.

For professional work, moving to a Pro, Premium, or Enterprise license removes these numerical bottlenecks entirely.

If you believe your mesh is small but the error persists, the Ansys Learning Forum is the best place to post your project files for a license check. Seeing the text means your license is working

If you are at a university, check if your lab has a "Research" license. These have much higher limits (often in the millions) or are completely "Unlimited."

The limits depend heavily on which version of Ansys you are running. As of the most recent releases, the standard limits for versions are: Structural (Ansys Mechanical): 128,000 nodes/elements. Fluid (Ansys Fluent / CFX): 512,000 cells/nodes. If you believe your mesh is small but

If you are seeing the message in your output file or solver console, you have encountered the built-in "governor" of an Ansys academic or entry-level license.

If you exceed these numbers, the solve will fail, and the message will change from "verified" to a "limit exceeded" error. 3. How to Manage Model Size As of the most recent releases, the standard

Understanding the "Ansys Product License Numerical Problem Size Limits Verified" Message

Ansys offers various licensing tiers ranging from free student versions to high-end enterprise packages. To keep the student versions accessible, Ansys limits the complexity of the models you can solve.

Remove small fillets, rounds, or decorative features that don't impact the global physics. These features often "hog" elements by forcing the mesher to create tiny cells in insignificant areas. Use Shell and Beam Elements
