Ansys Your Product License Has Numerical Problem Size Limits Verified _verified_

When the solver fails, open the .out or .log file. It will explicitly state: "The number of nodes [X] exceeds the maximum limit of [Y]." 4. How to Fix the Error

For a Student license in structural mechanics, the sum of the nodes and elements must be under the limit (e.g., 32,000). Do not check them independently.

. When your mesh exceeds these values, the solver is blocked from proceeding. Standard License Limits

If you cannot upgrade your license, you must reduce your element count without losing accuracy: When the solver fails, open the

This article explains exactly what this message means, why it appears, and how to resolve or work around it to keep your simulations running. What Does the Error Mean?

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.

Limited by the number of cells or nodes . Do not check them independently

If you are analyzing thin-walled structures, replace 3D solid bodies with (mid-surfaces) in SpaceClaim or DesignModeler. This reduces the number of elements from thousands to a manageable few. C. Utilize Symmetry

Use symmetry planes or axes to simulate only one-half, one-quarter, or one-eighth of the model. 2. Simplify the Geometry

When you attempt to solve a model, the software calculates the total size of your mesh. If that number exceeds the hardcoded limit embedded in your license file, the solver blocks the operation and displays this message. Why Are You Seeing This Message? There are three primary reasons this limit is triggered: 1. You Are Using an Academic Student Edition Standard License Limits If you cannot upgrade your

By following the guidelines and best practices outlined in this article, you can ensure that you are using ANSYS software efficiently and effectively, while also maximizing the value of your investment.

License limits are primarily based on and Element (or cell) counts. Once your mesh statistics cross these thresholds, the solver will refuse to proceed.

Sometimes the error manifests in confusing ways. One user ran a model with 559,995 elements and 782,941 nodes, well above typical student limits, and it ran fine initially before suddenly crashing with the "problem size" error. The investigation revealed that while the user intended to use a , the software had defaulted to checking out the Academic Teaching license , which lacked the capacity for that model size.
