Ansys Your Product License Has Numerical Problem Size Limits Verified ❲TESTED — 2026❳
You can check your limits without running a full solve:
Alternatively, in Workbench:
Ansys uses problem size limits to differentiate license tiers. Common license levels include:
| License Type | Typical Limit (DOFs) | | --- | --- | | Teaching (Student) | ~512 to 2,000 nodes/elements | | Research (e.g., CFD R2) | ~512,000 cells/nodes | | Professional | ~1–2 million DOFs | | Enterprise / Premium | Unlimited (or very high) | You can check your limits without running a full solve:
Your license file contains a parameter called ProblemSizeLimit or a feature-specific token limit. If your mesh exceeds that number, Ansys refuses to solve.
You generate a mesh. The process finishes without errors. But when you attempt to solve, ANSYS runs a pre-check, reads the license token, and aborts. The mesher may not check limits until the solver initializes.
The error message “ANSYS Your product license has numerical problem size limits verified” is intimidating, but it is not a dead end. It is a precise, informative signal from the software that you have reached a contractual boundary. By understanding the meaning of "verified," identifying your exact license type, and applying systematic model reduction or license upgrades, you can overcome this barrier. Alternatively, in Workbench: Ansys uses problem size limits
Remember: This warning is a sign of growth. Your simulation fidelity is outgrowing your current license tier—which is exactly the moment to either refine your modeling discipline or invest in greater capacity. Do not fear the message; decode it, solve it, and get back to breakthrough engineering.
Next Steps: Run ans_licinfo now. Check your current limits. Document them for your team. And the next time anyone in your organization sees that warning, you will be the expert who explains why “verified” is the most important word in the sentence.

Here’s a clear, informative content piece explaining how ANSYS enforces numerical problem size limits based on your product license. You can use this for internal documentation, a knowledge base article, or a team notification.
The Issue: You are attempting to run a simulation (likely a "pre-post" or "solver" task) that exceeds the size limit of your current license tier. Common Cause: Using a "Pre-Post" license to solve a large model, or having an older license file that doesn't recognize your current Ansys version limits. Immediate Fix: Check if you are using the correct license module (e.g., switching from "Pre-Post" to a full "Solver" license) or update your license file.
Proactive engineering is better than reactive debugging.
