Seeing the text means your license is working exactly as intended. It is a signal that your current model fits within the bounds of your specific software tier, allowing you to proceed with your simulation.
Understanding the "Ansys Product License Numerical Problem Size Limits Verified" Message
If you are at a university, check if your lab has a "Research" license. These have much higher limits (often in the millions) or are completely "Unlimited." Seeing the text means your license is working
When you initiate a solve, the software performs a . It counts the number of nodes and elements (for FEA) or cells (for CFD). If the count is within the allowed range, it prints this message as a "pass" notification and begins the calculation. 2. Common License Limits
If your part is symmetric, don't model the whole thing. Using allows you to model half, a quarter, or an eighth of the geometry, effectively doubling or quadrupling your allowable mesh density. Simplify Geometry These have much higher limits (often in the
The limits depend heavily on which version of Ansys you are running. As of the most recent releases, the standard limits for versions are: Structural (Ansys Mechanical): 128,000 nodes/elements. Fluid (Ansys Fluent / CFX): 512,000 cells/nodes.
Instead of a fine global mesh, use a coarse global mesh and apply or Inflation Layers only where the gradients are high (like at a bolt hole or a wing's leading edge). 4. Moving Beyond the Limits Instead of a fine global mesh
Restrictions usually apply to the number of primitives or mesh complexity.
If you are seeing the message in your output file or solver console, you have encountered the built-in "governor" of an Ansys academic or entry-level license.
Ansys offers various licensing tiers ranging from free student versions to high-end enterprise packages. To keep the student versions accessible, Ansys limits the complexity of the models you can solve.
