Log out reminder
Apply finer mesh controls only to areas of interest (e.g., stress concentrations, sharp corners) and keep the rest of the model coarser.
If you cannot resolve it using the steps above, use the command below to generate a detailed diagnostic report. You will need this to send to Ansys Support:
If you are at a university or company, ensure the software is pulling the correct license tier.
Ansys Academic and Student versions have built-in constraints to ensure the software is used for educational purposes rather than heavy industrial work. Ansys Student (Introductory): Typically limited to 32,000 nodes/elements for Structural (Mechanical) simulations and 512,000 cells/nodes for Fluid Dynamics (Fluent). Newer versions may allow up to for structural or nearly for CFD, but these vary by release. University Licenses: Limits vary by tier, such as for Intermediate, for Advanced, and for Research licenses.
To resolve this issue, you must either optimize your simulation model to fit within your current license limits or upgrade to a commercial or research license. Understanding License Limits

Can vary, but may also have limits compared to commercial versions. 2. Why Did I Exceed the Limit?
. If your node numbers are sparse (e.g., jumps from 10 to 5,000), the solver might think the problem is larger than it is. The "Latch" Bug:
Increase the minimum element size for the entire model.
Look for lines like: ansyslmd or feature entries. However, for detailed limits, use the .
