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

When you initiate a solve, the software performs a . It counts the number of nodes and elements (for FEA) or cells (for CFD). If the count is within the allowed range, it prints this message as a "pass" notification and begins the calculation. 2. Common License Limits

Many engineers get confused because their mesh metrics panel reads lower than 32k or 512k, yet the solver still crashes. This hidden inflation happens due to two primary technical factors: Contact and Boundary Elements

If you are at a university, check if your lab has a "Research" license. These have much higher limits (often in the millions) or are completely "Unlimited." When you initiate a solve, the software performs a

The limits vary significantly depending on the physics being simulated and the version of the software:

To manually assign a lower node number to a remote point's pilot node: These have much higher limits (often in the

If you'd like, I can provide more specific advice if you tell me:

If you once exceeded the limit and then reduced your mesh, Ansys sometimes "remembers" the failure. A common workaround is to Update Geometry from Source in an email

Here’s a useful response you can use (e.g., in an email, support ticket, or internal note) when dealing with ANSYS license limits related to problem size:

Check the startup printout or type a mesh info command to see the total . Step-by-Step Solutions to Fix the Error
