If your model has geometric and loading symmetry, you only need to solve a fraction of it.
Generally capped at 512,000 nodes/cells , though some newer versions (like 2025 R1) may allow up to 1 million cells .
Contact your ANSYS reseller to request a license feature upgrade (e.g., HPC Pack, larger problem size caps, or unlimited nodes). If your model has geometric and loading symmetry,
To verify your ANSYS license's numerical problem size limits, follow these steps:
By optimizing your mesh strategy, you can avoid the "numerical problem size limits" error and successfully complete your analysis within the limitations of the ANSYS student software. To verify your ANSYS license's numerical problem size
If you are analyzing thin-walled structures, replace 3D solid bodies with (mid-surfaces) in SpaceClaim or DesignModeler. This reduces the number of elements from thousands to a manageable few. C. Utilize Symmetry
Let’s look at practical situations where this error is most common. larger problem size caps
If your project requires high fidelity that exceeds these limits, your options are:
These numbers vary by version (v2024 vs v2023) and specific contract. Always verify via your license center.
Here are some common numerical problem size limits associated with ANSYS licenses:
