Ansys Your Product License Has Numerical Problem Size Limits Verified //top\\ -

Understanding the specific limits of your license is the first step to effective troubleshooting:

In structural shells, switching from higher-order (quadratic) elements to lower-order (linear) elements significantly reduces node count, though it may impact accuracy. 5. Moving Beyond the Limits

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.

To manually assign a lower node number to a remote point's pilot node: Understanding the specific limits of your license is

The numbers in the table above are standard guidelines. However, many users are confused when their model's node count seems well within the given limit, yet they still encounter the error. This is because the "check" mechanism is more sophisticated than a simple headcount.

When contact definitions or remote points are used, the node numbering scheme can jump to much higher numbers than what is shown in the mesh details. This means even a model with relatively few nodes can have a node ID exceeding the limit and trigger the error.

Whether you're a student pushing the boundaries of a free license or a researcher managing university seats, the error The root cause is almost always a mesh

If you cannot immediately upgrade your license, here are the most effective ways to bypass this error by shrinking your model. 1. Reduce Mesh Density (Coarsening) The most direct solution is to reduce the number of nodes.

When you configure bonded contacts, remote displacements, or remote moments, Ansys automatically injects underlying and surface effect elements during runtime. These elements do not appear in your initial mesh statistics but are pushed to the solver, instantly tipping your total node count over the license limit. The Node ID Gap (Renumbering Issue)

If you are running large-scale Finite Element Analysis (FEA) or Computational Fluid Dynamics (CFD) simulations in and encounter the error "your product license has numerical problem size limits verified," you have hit a fundamental constraint of your current licensing agreement. To manually assign a lower node number to
