Ansys Your Product License Has Numerical Problem Size Limits Verified ((exclusive)) Review

The most common cause of this error is inadvertently using a license to run a solver. Pre-Post licenses are cheaper and intended only for setup and post-processing; they have strict limits on problem size (often around 500k cells/nodes) if used to solve.

You have a moderate global mesh, but you add local refinement, contact elements, or submodeling. The total number of interacting DOFs balloons. Even if your node count seems safe, contact elements and multipoint constraints (MPCs) add hidden DOFs that trigger the limit. The most common cause of this error is

Proactive engineering is better than reactive debugging. The total number of interacting DOFs balloons

Do not panic. You have several options, ranging from simple workarounds to strategic licensing changes. Do not panic

In this comprehensive guide, we will dissect what this warning means, why it appears, how to verify your limits, and most importantly, how to resolve it without losing weeks of pre-processing work.

If your part is symmetrical, simulate only a half or quarter of it and use Symmetry Boundary Conditions to keep the mesh size within limits.
