Instead of a fine global mesh, use a coarse global mesh and apply or Inflation Layers only where the gradients are high (like at a bolt hole or a wing's leading edge). 4. Moving Beyond the Limits
Use midsurfaces to convert solid bodies into shell elements or use beam elements for thin supports. This drastically reduces node counts compared to 3D solid meshing. Instead of a fine global mesh, use a

ANSYS licenses often include —restrictions on the maximum number of degrees of freedom (DOFs), nodes, elements, or other solution-specific metrics. These limits are tied directly to your license tier (e.g., Academic, Professional, Enterprise). This document explains how to verify these limits within ANSYS and ensure your simulation complies.
