If you cannot upgrade your license immediately, you must optimize your model to fit within the "Problem Size" constraints: Error: “ANSYS Your product license has numerical problem
The most common cause of this error is inadvertently using a license to run a solver. Pre-Post licenses are cheaper and intended only for setup and post-processing; they have strict limits on problem size (often around 500k cells/nodes) if used to solve. Pre-Post licenses are cheaper and intended only for
The error message is a verification that your model exceeds the maximum node or element count allowed by your specific Ansys license. This is most common in free Student or restricted Academic versions. Understanding License Limits (2025/2026 Standards) The limits depend on the physics of your simulation:
Solid 3D elements (like HEX or TET) consume a massive number of nodes. Convert thin-walled 3D parts into .
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:
