Ansys Your Product License Has Numerical Problem Size Limits Verified _verified_

If you are a simulation engineer, you have likely encountered the dreaded pop-up or output message while solving a model in Ansys Fluent, Mechanical, or HFSS: “Your product license has numerical problem size limits verified” or a variation such as “License limits restrict the maximum problem size (number of nodes/cells).”

This generates a text file detailing exactly which license feature failed and why.

This article explores what this error means, its specific limitations, and how to resolve it to get your simulations running. 1. What Does "Numerical Problem Size Limits" Mean? If you are a simulation engineer, you have

The solver cannot proceed because the numerical matrix it needs to solve is larger than what the license allows. 2. Specific Limitations of Ansys License Versions

Why You Exceeded the Limit (Even When the Mesh Looked Small) What Does "Numerical Problem Size Limits" Mean

Here’s a clear, informative content piece explaining how ANSYS enforces numerical problem size limits based on your product license. You can use this for internal documentation, a knowledge base article, or a team notification.

Better yet, explicitly request the feature in the tab inside Workbench: deselect the capped licenses (e.g., "Mechanical Pro") and keep only "Mechanical Enterprise." Specific Limitations of Ansys License Versions Why You

A: No. It is an intentional feature of ANSYS licensing. The word “verified” confirms the system is working as designed.
