Ansys Your Product License Has Numerical Problem Size Limits Verified 【LEGIT · Tips】

Some lower-tier commercial licenses restrict the size of the mesh to encourage upgrading to more powerful, higher-cost packages. 2. The Nature of the Limit

Look for lines like: ansyslmd or feature entries. However, for detailed limits, use the .

Short "ANSYS: Your product license has numerical problem size limits verified."

If your research or professional project requires a higher fidelity than the "verified" limits allow, you have three primary paths: Some lower-tier commercial licenses restrict the size of

If your geometry and boundary conditions are symmetric, model only 12one-half 14one-fourth 18one-eighth of the geometry and apply . D. Reduce Element Order

Set a larger element size for these specific regions to strip away unnecessary nodes. 3. Utilize Geometric Symmetry Current model has 45,200 DOFs

The specific limits vary depending on the physics environment and the type of academic license being used. Physics Type Ansys Free Student Limit Higher Academic Tiers (e.g., Research) 32,000 nodes/elements Up to 512,000 nodes Fluids (CFD/Fluent) 512,000 nodes/cells No limit (on full licenses) Electromagnetics Specific limits vary by version Scaled based on license tier Common "Hidden" Triggers

The error message typically appears when a simulation model exceeds the hard constraints of a non-commercial Ansys license. This most commonly affects users of Ansys Student or Academic versions, where the software restricts the complexity of models to ensure the free version is used for educational purposes rather than professional-grade production.
