Product License Has Numerical Problem Size Limits Verified [verified] — Ansys Your

Increase the Element Size in Mesh details to coarsen the mesh.

If you require a complex model that cannot be sufficiently simplified, the only true solution is to upgrade your license.

If you are working on a university campus network, your institution might have tiered commercial-academic packages. According to the Ansys Forum documentation , boundaries scale by license type: 16,000 nodes Intermediate (ansysuh): 32,000 nodes Advanced (ansysrf): 128,000 nodes Research (aunivres): 512,000 nodes Hidden Triggers: When the Math Deceives You

A high number of contact pairs increases the computational load and, sometimes, the effective element count. 3. How to Resolve the Error (Actionable Steps) Increase the Element Size in Mesh details to

Note: Actual limits depend on contract and product version. Always verify with lmstat or /STATUS,LIMIT .

The “numerical problem size limits verified” error isn’t a bug—it’s a . Understanding it saves hours of debugging.

Decoding the Error: "Your Product License Has Numerical Problem Size Limits" According to the Ansys Forum documentation , boundaries

Add a small Python script in Workbench that queries:

Analyze a large, coarse model to find the region of interest, then create a smaller, highly refined submodel of just that area.

Ansys validates the license by checking the of the nodes, rather than just the mathematical sum of the active nodes. If you modify, slice, or delete sections of your geometry, you may only have 25,000 active nodes, but a few nodes might retain an internal ID of 35,001 . The license tool flags the ID 35,001 as exceeding the 32,000 limit and kills the run. Actionable Strategies to Resolve the Limit Error Always verify with lmstat or /STATUS,LIMIT

I can then provide specific mesh reduction steps or geometry clean-up techniques for your project. Share public link

This error directly relates to the licensing restrictions applied to specific versions of Ansys, primarily the Ansys Student or Ansys Academic versions. It does not necessarily mean your model is wrong, but that it is too large for the license to process.
