By following the guidelines and best practices outlined in this article, you can ensure that you are using ANSYS software efficiently and effectively, while also maximizing the value of your investment.
What are you performing? (e.g., Structural, CFD)
Generally restricted to 512,000 nodes or cells . By following the guidelines and best practices outlined
512,000 cells/nodes. (Newer versions may allow up to 1 million). 2. The Hidden "Trap": Why Your Small Model Failed
Some licenses check the highest node ID rather than just the total count. If you have 1,000 nodes but one is numbered "40,000," the solver may fail. 512,000 cells/nodes
Here is a blog post guide to understanding, diagnosing, and fixing this limitation.
If your visible mesh is well within the limits, hidden elements are the likely culprit. The Hidden "Trap": Why Your Small Model Failed
The limits vary significantly depending on the physics being simulated and the version of the software:
A high number of contact pairs increases the computational load and, sometimes, the effective element count. 3. How to Resolve the Error (Actionable Steps)
