Typically 32,000 nodes.
Ansys software is the global gold standard for engineering simulations. However, encountering the error message can completely halt your workflow.
Typically limited to 32,000 nodes/elements .
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
Verifying numerical problem size limits is essential for several reasons: Typically 32,000 nodes
Reduce the complexity of the model to lower the cell count naturally.
When applying hydrostatic pressure, additional SURF154 elements can push the total over the limit even with mesh count under 64K. The solution is to make the mesh even coarser to accommodate these hidden elements.
I can then provide specific mesh reduction steps or geometry clean-up techniques for your project. Share public link
: Academic Teaching licenses have higher limits than Student versions, while Commercial licenses generally feature unlimited problem size capabilities. Typically limited to 32,000 nodes/elements
Generally capped at 512,000 nodes/cells , though some newer versions (like 2025 R1) may allow up to 1 million cells .
Solid 3D elements (like HEX or TET) consume a massive number of nodes. Convert thin-walled 3D parts into .
The message " Your product license has numerical problem size limits verified
Running a complex simulation in ANSYS only to be stopped by the error message is a frustrating experience for engineers, researchers, and students alike. the common numerical limits are:
Boundary conditions, remote loads, or moments can add "hidden" connection elements to the total count at the start of a solve, pushing a "borderline" model over the limit. How to Resolve the Error
This error means your simulation model has exceeded the maximum geometric size allowed by your specific Ansys license tier. Ansys restricts the complexity of models by measuring the total number of mesh elements and nodes. When your mesh density surpasses these hard-coded boundaries, the solver automatically blocks the simulation from running. Mesh and Node Limits by Ansys License Tier
If your part is symmetrical, simulate only half (or a quarter) of it. This can instantly cut your node count by 50–75%. Use Shells and Beams:
It is important to note that other error messages like Request name electronics_desktop does not exist in the licensing pool or FlexNet Licensing error -16, 10009 alongside System Error10054 (WinSockConnection reset by peer) are related to a separate issue: license server connectivity problems, not numerical size limits.
For most Ansys Student versions, the common numerical limits are:
