Ansys Your Product License Has Numerical Problem Size Limits Verified Fixed Jun 2026

The specific limits depend on the version and type of analysis you are performing: Analysis Type Limit (Nodes/Elements) Structural (FEA) 32,000 – 128,000

32,000 nodes and elements combined. Some newer versions may allow up to 128,000.

The specific limits vary depending on the physics environment and the type of academic license being used. Physics Type Ansys Free Student Limit Higher Academic Tiers (e.g., Research) 32,000 nodes/elements Up to 512,000 nodes Fluids (CFD/Fluent) 512,000 nodes/cells No limit (on full licenses) Electromagnetics Specific limits vary by version Scaled based on license tier Common "Hidden" Triggers

If upgrading to a paid, uncapped commercial tier is not an immediate option, use these proven modeling strategies to compress your problem size without compromising structural data. ANSYS student software - ESSS

This message indicates that the model you are trying to solve exceeds the allowed number of nodes or elements stipulated by your license type, such as Academic, Student, or certain entry-level commercial packages.

A critical nuance, which is often the source of major frustration, is that the solver's check for license compliance is not based solely on the mesh you can see in your model tree. It also checks hidden, internal elements and nodes created by the software to handle complex tasks like contacts, remote forces, and moment loads. Furthermore, the check is often performed against the , not just the total count. This means that "gaps" in node numbering can create an ID number that is above the license limit, even if the total node count remains well under it.
