Ansys Your Product License Has Numerical Problem Size Limits Verified -
If you see this message, follow this hierarchy of solutions from simplest to most comprehensive.
Contact your Ansys reseller to add a “Max Problem Size Unlimited” add-on or upgrade your license from Professional to Enterprise. For temporary needs, consider elastic licensing (ELU) to rent high-tier tokens for 24 hours.
Your immediate goal is to drop below the threshold. Try these techniques:
After each reduction, check the solver output window for the elusive *** NOTE *** message that confirms the license limit and the current problem size. If you see this message, follow this hierarchy
For engineers, simulation analysts, and design professionals, ANSYS is the gold standard for finite element analysis (FEA), computational fluid dynamics (CFD), and electromagnetics. Few things disrupt a deep workflow like an unexpected error message. One of the most confusing yet critical warnings appears during meshing, solving, or post-processing:
“ANSYS Your product license has numerical problem size limits verified.”
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. After each reduction, check the solver output window
Proactive engineering is better than reactive debugging.
Understanding, Troubleshooting, and Overcoming Mesh & DOF Constraints in Ansys Simulations
If you are a simulation engineer, you have likely encountered the dreaded pop-up or output message while solving a model in Ansys Fluent, Mechanical, or HFSS: “Your product license has numerical problem size limits verified” or a variation such as “License limits restrict the maximum problem size (number of nodes/cells).” “ANSYS Your product license has numerical problem size
This notification is more than just an annoyance—it is a hard stop. It indicates that the scale of the simulation you are attempting to run exceeds the allowances of the specific Ansys license token you have checked out.
In this comprehensive guide, we will dissect what this warning means, why it appears, how to verify your limits, and most importantly, how to resolve it without losing weeks of pre-processing work.
Before troubleshooting, it is essential to translate the cryptic phrasing into plain English.
In short: Your current license restricts how large a simulation you can run, and ANSYS has just confirmed that your current model is either at or approaching that boundary.
