128,000 nodes/elements. (Note: Older versions were limited to 32k). Fluid Dynamics (Fluent):
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. 128,000 nodes/elements
The "your product license has numerical problem size limits verified" error is a common hurdle, particularly for academic users. By focusing on , leveraging symmetry , and ensuring your license entitlements are up to date , you can successfully run your simulations. Your simulation fidelity is outgrowing your current license
or duplicate the Model cell to a new Setup cell to reset the license check. Node ID Limits: In some cases, the error isn't the By focusing on , leveraging symmetry , and
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.
This specific error message is a rite of passage for almost every engineering student using the version. It occurs when your simulation mesh—the digital "grid" that breaks your model into tiny pieces for calculation—contains more nodes or elements than the free license allows.
When you encounter the error "Your product license has numerical problem size limits," it typically means your current model's mesh count
