Ansys Your Product License Has Numerical Problem Size Limits Verified |best| -

Sometimes you check your mesh and see 30,000 nodes—well under the 128,000 limit—yet it fails. Why? Contact Elements:

This article explains why this occurs, provides practical steps to resolve the issue, and explores strategies to manage simulation complexity within license constraints. What Does "Numerical Problem Size Limits Verified" Mean?

If you encounter this error while trying to solve, you must reduce the model's complexity to fit within the license window: Ansys Student - Engineering Information Technology

If you are running large-scale Finite Element Analysis (FEA) or Computational Fluid Dynamics (CFD) simulations in and encounter the error "your product license has numerical problem size limits verified," you have hit a fundamental constraint of your current licensing agreement. Sometimes you check your mesh and see 30,000

Solving the "Numerical Problem Size Limits" Error in Ansys Getting the error message

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.

Even if your visible mesh count is below the limit, the solver may still block you due to: Your product license has numerical problem size limits….. What Does "Numerical Problem Size Limits Verified" Mean

Typically limited to 256,000 nodes for FEA.

Run a 1000-node model. If that passes, your license works. The problem is purely model size. If even a small model fails, the license itself is corrupted or the feature is missing.

(e.g., Enterprise trial or cloud credits). However, a nonlinear transient analysis with 50 time
