Ansys Your Product License Has Numerical Problem Size Limits Verified -

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

If you are working on a complex simulation and suddenly see the message you’ve hit a structural wall in your workflow. This error isn’t a bug; it is a built-in restriction based on the specific license tier you are using. 1. Why Does This Error Occur?

Run a 1000-node model. If that passes, your license works. The problem is purely model size. If even a small model fails, the license itself is corrupted or the feature is missing.

This immediately cuts your node count by 50% to 75% without sacrificing local mesh density. 4. Switch to Shell or Beam Elements If you exceed these numbers, the solve will

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).”

Change the Element Order from Quadratic to Linear . This reduces the number of mid-side nodes, drastically lowering the total node count. 5. Reset the Solver Cell (If Limit was Previously Exceeded)

A deliberate, successful validation that your model exceeds the license's contractual boundary. ANSYS is complying with its license terms. Therefore, no amount of reinstalling or toggling settings will bypass it—unless you change the license or reduce the model size. This error isn’t a bug; it is a

3D volume limit is 64,000 elements; 2D limit is 2,000 triangles. Rocky (DEM) 32,000 particles Particle count limit is 32k regardless of shape. Common "Hidden" Causes

A: Yes – 32,000 nodes/elements. The message appears identically.

Expand the tab to view your exact Nodes and Elements count. For Ansys Fluent (CFD) Open Fluent or Ansys Meshing . Go to the Console window. Run a 1000-node model

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.

Maximum 128,000 nodes or elements. Fluid Dynamics (CFD): Maximum 512,000 cells or nodes.

You have a moderate global mesh, but you add local refinement, contact elements, or submodeling. The total number of interacting DOFs balloons. Even if your node count seems safe, contact elements and multipoint constraints (MPCs) add hidden DOFs that trigger the limit.
