Ansys Your Product License Has Numerical Problem Size Limits Verified Jun 2026

Instead of a global fine mesh, use Local Mesh Sizing . Keep the mesh coarse in non-critical areas and fine only where stresses or gradients are high.

If you see this message, follow this hierarchy of solutions from simplest to most comprehensive.

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

Instead of a fine global mesh, use a coarse global mesh and apply local mesh refinement only on critical areas (edges, fillets, contact regions).

Even if your displayed mesh count is below the limit, the error can trigger due to: Your product license has numerical problem size limits….. Open a command prompt/terminal as Administrator and run:

In Mechanical, the solver creates "contact elements" at runtime to handle interactions between parts. These are invisible in your initial mesh count but toward the license limit. The "Ghost" Limit:

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.

Typically 128,000 nodes.
