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

license, which has hard-coded limits on the number of nodes or elements your model can contain

If you encounter this error, you need to reduce the complexity of your simulation model to stay within the permitted limits. Here are several effective strategies: 1. Optimize and Refine the Mesh (Crucial)

Common license types and their typical limits (may vary by version and specific contract):

Change the mesh element order from Quadratic to if high precision on stress concentration is not required. Note: This may reduce accuracy. E. Check "Node Offset" Settings license, which has hard-coded limits on the number

Poorly shaped elements (high skewness) can force the solver to create more nodes than necessary. Improve mesh quality to reduce the total element count, as discussed on cfdland . 4. Summary Table of Solutions Apply Local Sizing Reduce total node count Geometry Remove fillets/small parts Simplify geometry Symmetry Cut model in half/quarter Reduce elements by Dimension Use 2D Model drasitcally reduce numerical size Solver Node Renumbering Keep IDs under 32k

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

Here is a blog post guide to understanding, diagnosing, and fixing this limitation. Note: This may reduce accuracy

Limited to 32,000 nodes or elements .

If your engineering problems require high-fidelity, uncompromised meshes, you have outgrown your current tier. You will need to contact your Ansys account manager or channel partner to upgrade from Student to Academic, or from Pro/Premium to an Enterprise commercial license. To help narrow down the solution, tell me:

Use instead of Tetrahedral meshes where possible. Hex elements fill space more efficiently, requiring fewer total elements for the same volume. 4. Simplify Geometry (Defeaturing) Improve mesh quality to reduce the total element

By optimizing your mesh strategy, you can avoid the "numerical problem size limits" error and successfully complete your analysis within the limitations of the ANSYS student software.

*** WARNING *** Your current license (ANSYS Professional) limits DOFs to 32,000. Current model has 45,200 DOFs. Solution will not proceed.
