Has Numerical Problem Size Limits Verified _hot_: Ansys Your Product License
This error message typically appears in Ansys products (like Fluent, CFD, or Mechanical) when the license manager detects that the problem you are trying to solve requires more resources (cells, nodes, or equations) than your specific license type permits.
Here is a useful guide on how to interpret, troubleshoot, and resolve this error.
Scenario C: Nonlinear or Transient Steps
In a static analysis, you might be under the limit. However, a nonlinear transient analysis with 50 time steps and 10 substeps per step multiplies the effective problem size. ANSYS counts the peak numerical problem size, not the average. This error message typically appears in Ansys products
1. Reduce the Problem Size (Immediate Workaround)
- Coarsen the mesh: Use global mesh controls (Element Size = 2x current) or reduce curvature refinement.
- Use symmetry: Model 1/4 or 1/2 of the geometry.
- Change element order: Reduce from quadratic (10-node tet) to linear (4-node tet). This cuts nodes by ~70%.
Decoding the Warning: “ANSYS Your Product License Has Numerical Problem Size Limits Verified”
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:

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.
