You will typically encounter this warning during three specific phases:
Ansys uses problem size limits to differentiate license tiers. Common license levels include:
| License Type | Typical Limit (DOFs) |
| --- | --- |
| Teaching (Student) | ~512 to 2,000 nodes/elements |
| Research (e.g., CFD R2) | ~512,000 cells/nodes |
| Professional | ~1–2 million DOFs |
| Enterprise / Premium | Unlimited (or very high) |
Your license file contains a parameter called ProblemSizeLimit or a feature-specific token limit. If your mesh exceeds that number, Ansys refuses to solve.
Sometimes the interface enforces a stricter check than the solver. Try launching the solver directly:
fluent 3ddp -g -t4 -i journal.jou
Or for Mechanical:
ansysXX -dis -b -m 4 -i input.dat -o output.out
The batch flag (-b) sometimes bypasses immediate size verification (not a full bypass, but avoids GUI overhead).
