Ansys Your Product License Has Numerical Problem Size Limits Verified [best]
A: Partially. You could run component-level analyses (e.g., one part at a time) and combine results manually. However, ANSYS checks the peak simultaneous DOFs during solution. You cannot run a full assembly.
If symmetry had not been possible, her alternative would be requesting an Academic Research license token from her department.
✅ Run /STATUS,LIMIT in APDL before solve. ✅ Compare model DOFs with license max. ✅ Check HPC license for core/GPU limits. ✅ For CFD: verify cell count against FLUENT license ( report cell count ).
Ansys implements strict limits on non-commercial packages to prevent their use in large-scale industrial projects. These boundaries differ heavily based on the type of physics you are solving: Physics Module Node / Element / Cell Limit (Ansys Mechanical) 32,000 nodes/elements total A: Partially
This instantly reduces your node and element count by 50% to 75%. 2. Apply Mesh Controls and Sizing
When contact definitions or remote points are used, the node numbering scheme can jump to much higher numbers than what is shown in the mesh details. This means even a model with relatively few nodes can have a node ID exceeding the limit and trigger the error.
In simple terms, refers to the number of degrees of freedom (DOFs) in your simulation. You cannot run a full assembly
Limited by the number of mesh elements or unknowns .
Limits often apply to the number of objects or the mesh density depending on the specific solver (HFSS vs. Maxwell).
Contact your ANSYS channel partner to discuss an upgrade to a higher tier or to add HPC Packs which unlock larger solve capabilities. ✅ Compare model DOFs with license max
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
For most Ansys Student versions, the common numerical limits are:
| License Type | Typical Node/Elements Limit | DOF Limit (Approx.) | | :--- | :--- | :--- | | ANSYS Student | 32,000 nodes/elements | ~100,000 DOFs | | ANSYS Academic Teaching | 512,000 nodes/elements | ~1.5M DOFs | | ANSYS Academic Research | 2,000,000+ (varies) | ~4M-8M DOFs | | ANSYS Professional | 20,000 nodes/elements | ~60,000 DOFs | | ANSYS Enterprise/ Premium | Unlimited (hardware dependent) | None |
