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

Leo sat hunched over his laptop at 2:00 AM, the blue light reflecting off his glasses. He was finishing his final project: a stress analysis on a custom-designed car jack. He had spent hours in refining the geometry until it was perfect—every bolt, every chamfer, and every small fillet was meticulously modeled.

Understanding what causes this threshold violation and learning the hidden diagnostic behaviors of the solver will help you bypass this error and run successful simulations. Understanding the Hard Licensing Limits

The "numerical problem size" refers to the total number of nodes, elements, or bodies in your FEA (Finite Element Analysis) or CFD (Computational Fluid Dynamics) model. When a simulation exceeds these predefined limits, the solver stops the analysis to ensure compliance with the license agreement. Key Takeaways of the Error:

Use geometry tools to remove small, unnecessary features that force a fine mesh. 2. Utilize Symmetry Leo sat hunched over his laptop at 2:00

Increase the value to create larger, fewer elements.

Sometimes your mesh appears to be under the limit, but you still trigger the error due to: Your product license has numerical problem size limits….. Key Takeaways of the Error: Use geometry tools

If you are confident you have the correct license type, verify that your model hasn't accidentally grown beyond the licensed limit.

Matt, the ANSYS Student license is limited to 512K cells/nodes for a CFD model. A full license has no such limitation. Ansys Innovation Space Icepak Student Limitations - Ansys Help

Generally capped at 512,000 cells. B. Ansys Academic Research/Teaching If you are at a university

Check your mesh size → Compare to your license tier → Coarsen, symmetrize, or upgrade.

If you are at a university, check if your lab has a "Research" license. These have much higher limits (often in the millions) or are completely "Unlimited."

Slice your model into halves or quarters using the tool in SpaceClaim or DesignModeler.
