Decoding the Warning: "Ansys Your Product License Has Numerical Problem Size Limits Verified"
Understanding, Troubleshooting, and Overcoming Mesh & DOF Constraints in Ansys Simulations
Commercial Licensing: For professional work, moving to a Pro, Premium, or Enterprise license removes these numerical bottlenecks entirely.
Short "ANSYS: Your product license has numerical problem size limits verified."
Method 2: Check license.log or Product Output
Right before the "verified" warning appears, the solver console usually prints a line like:
Test with a Known Small Model:
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.
- Check Your License Details: Log in to your ANSYS account or consult your license documentation to determine your product's limits.
- Launch ANSYS: Start your ANSYS product, such as ANSYS Mechanical or ANSYS Fluent.
- Model Setup: Set up your simulation model, including meshing, boundary conditions, and material properties.
- Mesh Statistics: Check the mesh statistics, such as the number of elements, nodes, and degrees of freedom.
- Compare with License Limits: Compare your model's statistics with your license limits to ensure you're within the allowed range.
Upgrade license temporarily (e.g., Enterprise trial or cloud credits).
