If you exceed the numerical problem size limits associated with your ANSYS license, you may encounter:
Open a command prompt/terminal as Administrator and run:
Apply to the cut faces. This effectively doubles or quadruples your allowable mesh density for the same node count. 4. Simplify Geometry and Mesh Controls
Are you performing a or CFD (fluent/CFX) analysis? Licensing Resources - Ansys If you exceed the numerical problem size limits
Sometimes, Ansys is looking at the wrong license server or file.
When you encounter the error "Your product license has numerical problem size limits," it typically means your current model's mesh count
To confirm exactly what your license allows, follow these steps: Simplify Geometry and Mesh Controls Are you performing
Before making changes, confirm how far you are over the limit. In the tree, select the Mesh branch. In the Details window, expand the Statistics section. Check the total number of Nodes and Elements .
you are currently using (e.g., Student, Academic Research, PrepPost)?
The type of element you choose directly impacts the node budget. In the tree, select the Mesh branch
To avoid losing time, you should proactively verify your license's capabilities:
Expand the tab to view your exact Nodes and Elements count. For Ansys Fluent (CFD) Open Fluent or Ansys Meshing . Go to the Console window.
If a model fails once, the error can sometimes "stick" in the Setup cell. Try duplicating the Model cell and creating a fresh Setup cell to reset the license check. Your product license has numerical problem size limits…..
When the solver fails, open the .out or .log file. It will explicitly state: "The number of nodes [X] exceeds the maximum limit of [Y]." 4. How to Fix the Error
Global element sizes can be increased in areas where stress or fluid gradients are low.
