Look for lines like: ansyslmd or feature entries. However, for detailed limits, use the .

This is a common paradox. You may have solved a 1M node model last week, but today you get the “limits verified” error on a 600k node model. The reasons include:

| License Type | Max DOFs (Structural) | Max Cells (CFD) | HPC Cores | |-----------------------------|------------------------|------------------|------------| | ANSYS Academic Teaching | 512,000 | 1M cells | 4 | | ANSYS Academic Research | Unlimited (with HPC) | Unlimited | 64+ | | ANSYS Professional | 32,000 | N/A | 2 | | ANSYS Enterprise | Unlimited | Unlimited | 16 (base) | | ANSYS Mechanical Pro | 128,000 | N/A | 4 |
