Ansys Your Product License Has Numerical Problem Size Limits Verified Access

If you recently renewed your license or installed a new version of Ansys, the error might be due to an outdated license file ( license.lic or ansyslmd.lic ).

Use geometry tools to remove small, unnecessary features that force a fine mesh. 2. Utilize Symmetry

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.

To verify your ANSYS license's numerical problem size limits, follow these steps: If you recently renewed your license or installed

You are attempting to run a simulation (likely a "pre-post" or "solver" task) that exceeds the size limit of your current license tier. Common Cause: Using a "Pre-Post" license to solve a large model, or having an older license file that doesn't recognize your current Ansys version limits. Immediate Fix: Check if you are using the correct license module (e.g., switching from "Pre-Post" to a full "Solver" license) or update your license file.

In short: Your current license restricts how large a simulation you can run, and ANSYS has just confirmed that your current model is either at or approaching that boundary.

Increase the minimum element size for the entire model. Utilize Symmetry Run a 1000-node model

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

Eliminate fasteners, fillets, or complex logos that do not significantly affect the overall structural performance or fluid flow of the assembly. Long-Term Strategies for Large Models

This instantly reduces your node and element count by 50% to 75%. 2. Apply Mesh Controls and Sizing If even a small model fails, the license

Are you currently working on a or fluids project, and do you know your current node count ?

Apply finer mesh controls only to areas of interest (e.g., stress concentrations, sharp corners) and keep the rest of the model coarser.

When your model exceeds the threshold defined in your license file (e.g., ANSYSACADEMICTEACHING ), the solver triggers the "numerical problem size limits verified" message.
