Ansys Your Product License Has Numerical Problem Size Limits Verified
If you cannot resolve it using the steps above, use the command below to generate a detailed diagnostic report. You will need this to send to Ansys Support:
The "Your product license has numerical problem size limits verified" error in Ansys is a clear, if sometimes confusing, message about exceeding your license's capacity. The root cause is almost always a mesh with too many nodes and elements, often compounded by hidden contact elements or high node IDs. By understanding your license's specific limits, methodically verifying your model's metrics, and applying the appropriate model reduction techniques, you can efficiently resolve this error and continue your simulation work. If the limitations of your current license are a recurring barrier, evaluating a move to an Academic Research license, a full Commercial license, or a flexible Elastic Licensing model is the most effective long-term solution.
What of Ansys are you running? (Student, Research, Commercial?) What is the current node or cell count of your mesh? Which solver are you using? (Mechanical, Fluent, HFSS?) If you cannot resolve it using the steps
Instead of a global fine mesh, use Local Mesh Sizing . Keep the mesh coarse in non-critical areas and fine only where stresses or gradients are high.
The "numerical problem size" refers to the total number of nodes, elements, or bodies in your FEA (Finite Element Analysis) or CFD (Computational Fluid Dynamics) model. When a simulation exceeds these predefined limits, the solver stops the analysis to ensure compliance with the license agreement. Key Takeaways of the Error: (Student, Research, Commercial
This error means your simulation model has exceeded the maximum geometric size allowed by your specific Ansys license tier. Ansys restricts the complexity of models by measuring the total number of mesh elements and nodes. When your mesh density surpasses these hard-coded boundaries, the solver automatically blocks the simulation from running. Mesh and Node Limits by Ansys License Tier

This error directly relates to the licensing restrictions applied to specific versions of Ansys, primarily the Ansys Student or Ansys Academic versions. It does not necessarily mean your model is wrong, but that it is too large for the license to process.
If upgrading to a paid, uncapped commercial tier is not an immediate option, use these proven modeling strategies to compress your problem size without compromising structural data. ANSYS student software - ESSS
