Ansys Your Product License Has Numerical Problem Size Limits Verified -

You can check your limits without running a full solve:

If you are using a university-hosted network license via the Ansys Client Licensing Settings , your system checks out a specific feature profile: : Limit of 16,000 nodes . Ansys University Intermediate : Limit of 32,000 nodes . Ansys University Advanced : Limit of 128,000 nodes . Ansys Research License (aunivres) : Limit of 512,000 nodes . 🔍 The Hidden Trap: "Node ID" Inflation

Cut your model in half (2D symmetry) or quarter (3D symmetry) and apply symmetry constraints to the cut faces. This can reduce node count by 50% to 75% or more. 3. Switch to Shell or Beam Elements You can check your limits without running a

That PROBLEMSIZE=2000000 means 2 million DOFs. If it’s missing or lower than expected, contact your Ansys representative.

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

If the straightforward solutions fail, consider these advanced steps: do not simulate the entire structure.

When your license is "verified," the Ansys license manager checks the current model size against the entitlement. If the model exceeds the threshold (e.g., 512,000 nodes for a "Mechanical Professional" license), the solver stops and returns the warning.

To effectively resolve this issue, you must first know the specific limits associated with your license. Here is a breakdown for the most common license types:

If your CAD model is symmetric, do not simulate the entire structure.
