Ansys Your Product License Has Numerical Problem Size Limits Verified Jun 2026
Numerical problem size limits refer to the maximum number of elements, nodes, or degrees of freedom that your ANSYS license can handle. These limits vary depending on the specific ANSYS product and license type you have. Exceeding these limits can lead to inaccurate results, incomplete simulations, or even software crashes.
After verification, your current ANSYS license imposes numerical limits on problem size (e.g., number of nodes/elements, DOF, or contact pairs). Once these limits are exceeded, the solver may:
Seeing the text means your license is working exactly as intended. It is a signal that your current model fits within the bounds of your specific software tier, allowing you to proceed with your simulation.
This guide explains why this licensing error occurs, breaks down the specific node and mesh limits for different Ansys tiers, and provides actionable steps to resolve the issue. Understanding the Error Numerical problem size limits refer to the maximum
The mesh statistics visible in Ansys Mechanical do not show all elements created during solution. Contact definitions generate hidden contact elements, and remote force/pressure objects create SURF154 elements that add to the count but aren't visible in the mesh statistics.
A: Primarily solving. But some post-processing features (e.g., path plots, slice planes, result extrapolation) may also check limits if they require rebuilding the full solution matrix.
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 This guide explains why this licensing error occurs,
Click on Mesh in the outline tree. Look at the Details View window at the bottom left. Expand the Statistics section to view the exact number of nodes and elements.
The flagship tier. It features completely unlimited node and element sizes, restricted only by your hardware RAM and computing power. How to Verify Your Current Model Size
When you are stuck with the error, follow this checklist: Limits vary by physics and version
This isn't necessarily an error, but rather a confirmation that the software has checked your model size against the restrictions of your specific license tier. 1. Why Am I Seeing This?
Limits often apply to the number of objects or the mesh density depending on the specific solver (HFSS vs. Maxwell).
Limits vary by physics and version, but general caps for the Ansys Student version are: 128,000 nodes/elements. Fluid Physics (Fluent): 512,000 cells/nodes. Ansys Motion: 100,000 nodes per flexible body. Step-by-Step Resolution Guide
To resolve this issue, you must either optimize your simulation model to fit within your current license limits or upgrade to a commercial or research license. Understanding License Limits
