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

The error message "Your product license has numerical problem size limits verified" typically appears when a simulation model exceeds the hard constraints of a non-commercial Ansys license. This most commonly affects users of Ansys Student or Academic versions, where the software restricts the complexity of models to ensure the free version is used for educational purposes rather than professional-grade production. Core Limits by License Type

If you have seen this message, your simulation has stopped dead in its tracks. You are likely frustrated, confused, and worried about your project deadline. This article will dissect every component of that warning—what it means, why it happens, and exactly how to resolve it—so you can move from a licensing bottleneck back to high-fidelity simulation. The error message "Your product license has numerical

How ANSYS Enforces Numerical Size Limits

Depending on your license, ANSYS may limit: Identify your license’s exact node/cell limit using lmstat

(Replace <Installation_Path> with your actual Ansys installation directory, e.g., C:\Program Files\ANSYS Inc\v241). For structures: Use submodeling

Whether you're a student pushing the boundaries of a free license or a researcher managing university seats, the error

1. Identify your license’s exact node/cell limit using lmstat or the solver log.
2. Coarsen the mesh or apply symmetry to fit within the cap.
3. Force checkout of a higher-tier license via Preferences.
4. Consider submodelling or domain decomposition.
5. If cost-effective, upgrade to an Enterprise license for unlimited problem size.

• For structures: Use submodeling. Solve a coarse global model, then map boundary conditions to a detailed local model.
• For CFD: Use sliding mesh or interface boundaries to split into half the cell count per license.
