Ansys Your Product License Has Numerical Problem Size Limits Verified -

Do not guess. Run the ANSYS License Management Center utility (ans_licinfo or lmstat). Identify exactly which product feature is checked out (e.g., ansys , mech, fluent). Look for keywords like _teaching, _research, _pro, or _entry. Knowing the exact license feature explains the limit.

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.

Instead of one giant model, run multiple linked analyses:

User: Maria, graduate researcher in mechanical engineering. Model: Turbine blade thermal-stress analysis. License: ANSYS Academic Teaching (limit: 512k nodes). Error: “ANSYS Your product license has numerical problem size limits verified.” Solver output: License limit: 500,000 nodes. Current model: 508,242 nodes.

Resolution path:

If symmetry had not been possible, her alternative would be requesting an Academic Research license token from her department.

If you see "Your product license has numerical problem size limits": Do not guess

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.

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. Instead of one giant model, run multiple linked

Here’s a useful response you can use (e.g., in an email, support ticket, or internal note) when dealing with ANSYS license limits related to problem size:

Subject: ANSYS License Numerical Problem Size Limits – Verified & Action Steps

After verification, your current ANSYS license imposes numerical limits on problem size (e.g., number of nodes/elements, DOF, or contact pairs). Once these limits are exceeded, the solver may:

Common limits by license type (examples):

What to do next:

To permanently resolve recurring limit issues:
Contact your ANSYS reseller to request a license feature upgrade (e.g., HPC Pack, larger problem size caps, or unlimited nodes).

The error message "Your product license has numerical problem size limits" is a verification that your model exceeds the maximum node or element count allowed by your specific Ansys license. This is most common in free Student or restricted Academic versions. Understanding License Limits (2025/2026 Standards) The limits depend on the physics of your simulation:

Structural Analysis (Mechanical): Typically limited to 128,000 nodes/elements in current student versions (previously 32,000).

Fluid Dynamics (Fluent/CFX): Typically limited to 512,000 cells/nodes. Recent versions like 2025 R1 may allow up to 1 million cells but may restrict solutions to a single CPU core. Ansys Motion: Limited to 100,000 nodes per flexible body. Why You Get the Error (Even if Under the Limit)

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…..

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. If symmetry had not been possible, her alternative

If you consistently hit the limit, your engineering needs have outgrown your license type. Contact your ANSYS reseller or internal IT/license administrator. Ask for a quote to upgrade:

✅ Run /STATUS,LIMIT in APDL before solve.
✅ Compare model DOFs with license max.
✅ Check HPC license for core/GPU limits.
✅ For CFD: verify cell count against FLUENT license (report cell count).
