When your model exceeds the threshold defined in your license file (e.g., ANSYSACADEMICTEACHING), the solver triggers the "numerical problem size limits verified" message.

is a common hurdle, especially for students and researchers using academic or introductory versions of Ansys. Consider converting 3D solid bodies into midsurface shell

3. Update the License File

If you recently renewed your license or installed a new version of Ansys, the error might be due to an outdated license file (license.lic or ansyslmd.lic).

Solid models eat up nodes quickly. Consider converting 3D solid bodies into midsurface shell models beam models Ansys SpaceClaim ANSYS will output:

Method 4: Check Pre-Solver Warnings

When starting a solve, ANSYS will output:
