Limits Verified — Ansys Your Product License Has Numerical Problem Size

If you are confident you have the correct license type, verify that your model hasn't accidentally grown beyond the licensed limit.

In simple terms, numerical problem size refers to the number of degrees of freedom (DOFs) in your simulation.

When Ansys says your license has a “verified limit,” it means your current license token only permits simulations up to a certain DOF count.

Seeing “ansys your product license has numerical problem size limits verified” is not the end of your simulation—it is a signal. It tells you that you have outgrown the boundaries of your current license tier or that you need to refine your meshing strategy.

Immediate action items:

Remember, the “verified” term means the license manager has checked and confirms a mismatch. It is not a bug—it is a feature designed to enforce commercial boundaries. By understanding these boundaries, you can either work creatively within them or make a data-driven case to management for a license upgrade.

This message indicates that your Ansys Student or Academic license has restricted the number of nodes or elements you can solve. When your model exceeds these pre-defined limits, the solver is programmed to stop before the simulation begins. Standard License Limits

For most Ansys Student versions, the common numerical limits are: If you are confident you have the correct

Structural Physics: 32,000 nodes and elements combined. Some newer versions may allow up to 128,000.

Fluid Physics (CFD): 512,000 cells and nodes combined. Recent updates may support up to 1,000,000 cells. Electromagnetics (Maxwell): 64,000 elements for 3D volume. Why the Error Appears (Even if Mesh Looks Small)

Even if your displayed mesh count is below the limit, the error can trigger due to: Your product license has numerical problem size limits…..


ANSYS licenses often include numerical problem size limits—restrictions on the maximum number of degrees of freedom (DOFs), nodes, elements, or other solution-specific metrics. These limits are tied directly to your license tier (e.g., Academic, Professional, Enterprise). This document explains how to verify these limits within ANSYS and ensure your simulation complies. When Ansys says your license has a “verified


Let’s look at practical situations where this error is most common.

| License Product | Package Name | Typical Node/Cell Limit | | :--- | :--- | :--- | | Mechanical Pro | mechpro | 512,000 nodes | | Mechanical Enterprise | mechent | Unlimited (RAM dependent) | | Fluent (Teaching) | flu_tu | 16,384 cells | | Fluent (Research) | flu_res | 5 million cells | | CFD Premium | cfd_pre | 5 million cells | | CFD Enterprise | cfd_ent | 15 million cells | | HFSS (Academic) | hfss_acad | 150,000 tetrahedra |

Important: These numbers vary by version (v2024 vs v2023) and specific contract. Always verify via your license center.
