Reduces the required mesh elements by up to 50%. 2. Manage CAD Complexity Defeature: Remove tiny screw threads, fillets, and logos. It is vital to know the limits of
| Problem | Likely cause | Solution | |---------|--------------|----------| | "Mesh limit exceeded" | Geometry too complex | Simplify curves (use polygons), reduce air box size | | Simulation never finishes | Too fine mesh or wide sweep | Reduce sweep points, lower convergence criteria (ΔS=0.05) | | Port doesn't solve | Port touches Perfect E | Move port or re-assign boundaries | | No radiation pattern | No radiation boundary | Assign air box as Radiation or PML | | Cannot save project | Project size > limit | Delete field plots, reduce mesh operations | Manage CAD Complexity Defeature: Remove tiny screw threads,
