Ansys: Your Product License Has Numerical Problem Size Limits Verified - What It Means and How to Fix It

This notification is more than just an annoyance—it is a hard stop. It indicates that the scale of the simulation you are attempting to run exceeds the allowances of the specific Ansys license token you have checked out.

Open the ANSYS License Management Center . Under the "View Status" or "License File" tabs, you can see the specific features (increments) enabled. Ansys: Your Product License Has Numerical Problem Size

Remove small fillets, holes, or decorative features that force the mesher to create unnecessary elements.

A common point of confusion is the difference between the actual node count displayed in the mesh details and the highest node ID number in the model. The limitation is not simply about the number of nodes shown, but that the (e.g., 32K for structural student licenses). Under the "View Status" or "License File" tabs,

Maria, graduate researcher in mechanical engineering. Model: Turbine blade thermal-stress analysis. License: ANSYS Academic Teaching (limit: 512k nodes). Error: “ANSYS Your product license has numerical problem size limits verified.” Solver output: License limit: 500,000 nodes. Current model: 508,242 nodes.

As an engineer or researcher working with complex simulations, you rely on powerful software tools like Ansys to analyze and optimize your designs. However, when working with large-scale simulations, you may encounter a message that reads: "Ansys: Your product license has numerical problem size limits verified." This message can be concerning, especially if you're in the middle of a critical project. In this article, we'll explore what this message means, why it occurs, and how to address it to ensure smooth and efficient simulations. The limitation is not simply about the number

Numerical problem size limits are an essential consideration when working with ANSYS software. Understanding these limits and their implications can help you optimize your simulations, ensure accurate results, and make the most of your ANSYS license. By verifying your license's problem size limits, following best practices, and exploring mitigation strategies, you can efficiently and effectively utilize ANSYS software for your engineering simulation needs.

If your model has axial symmetry or is a thin-walled structure, consider using 2D Plane Stress, 2D Plane Strain, or Axisymmetric elements. This drastically reduces node counts.

This forces Ansys to use a smaller, user-defined node ID for the pilot node. If the first attempt doesn't work, try an even lower number like 500 to stay well within the node cap.

Increase the minimum element size for the entire model.
