Ansys Your Product License Has Numerical Problem Size Limits Verified

Different ANSYS licenses have varying "Numerical Problem Size Limits" based on the number of or elements (or a combination of both) you are permitted to solve. The error message is essentially a safety check: the software recognizes that proceeding would violate its own licensing agreement.

Using a small element size across the entire geometry instead of only where necessary.

Depending on your situation, use the following strategies to resolve the issue: Check Your License Preferences

Contact your Ansys representative to explore higher-tier licensing that offers increased or unlimited node capacities. Depending on your situation, use the following strategies

Replace a Remote Force with a simpler Pressure or Force applied directly to the face. If you must use remote points, ensure the node numbers assigned to their pilot nodes are not arbitrarily high.

Typically 128,000 nodes.

Analyze a large, coarse model to find the region of interest, then create a smaller, highly refined submodel of just that area. Typically 128,000 nodes

In CFX, you can run the solver separately from the pre-processor. The license check occurs at solver start—using a different feature set may allow larger sizes.

The most effective way to reduce problem size is to modify your model's geometry and meshing strategy:

This message is an informational alert or error indicating that your current Ansys license restricts the size of the simulation model you can solve. Ansys measures the "problem size" using specific mathematical metrics based on the type of simulation: 000 nodes. Analyze a large

While less common in Workbench, the APDL solver allows for the use of super elements to handle larger, complex substructures. 5. When to Upgrade Your License
