Verification examples

These verification problems show QuickField accuracy for different types of problems. For fair comparison with other methods please, keep in mind that Finite Element Method accuracy is highly dependent on the mesh size. QuickField simulation accuracy in most cases may be increased simply by automatic mesh improvement procedure (available in Professional version only).
