If you once ran a simulation that was too big, Ansys sometimes "remembers" the error. Even after reducing the mesh, the setup cell may need a reset. 5 Pro-Tips to Fix the Error 1. Compress and Renumber Your Mesh If your problem is sparse Node IDs, you can "compact" them. Right-click on Mesh Numbering Compress Node Numbers Right-click Mesh Numbering and select Renumber Mesh 2. Simplify Geometry (Shells and Beams)
If your cumulative node count is under 32,000 but the highest ID is bloated, compress the numbering sequence: Licensing Resources - Ansys
Whether you're a student pushing the boundaries of a free license or a researcher managing university seats, the error
Do not panic. You have several options, ranging from simple workarounds to strategic licensing changes. If you once ran a simulation that was
:
A: Two possibilities:
Contact your ANSYS reseller to request a license feature upgrade (e.g., HPC Pack, larger problem size caps, or unlimited nodes). Compress and Renumber Your Mesh If your problem
. This drastically reduces the node count while maintaining accuracy for thin-walled or long, slender structures. 3. Use Symmetry
This option primarily affects nodes created by the mesher, not necessarily remote point nodes.
Your immediate goal is to drop below the threshold. Try these techniques: You have several options, ranging from simple workarounds
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.
When you see the full, dreaded error message it is a definitive statement that your simulation contains more nodes and elements than your current license allows.
You may encounter errors like "Saving is disabled for models larger than 50 bodies or 300 faces" if you are using an academic version for complex assemblies. 3. How to Resolve: "Numerical Problem Size Limits"
You are attempting to run a simulation (likely a "pre-post" or "solver" task) that exceeds the size limit of your current license tier. Common Cause: Using a "Pre-Post" license to solve a large model, or having an older license file that doesn't recognize your current Ansys version limits. Immediate Fix: Check if you are using the correct license module (e.g., switching from "Pre-Post" to a full "Solver" license) or update your license file.
