Enhanced models of lumped elements (LE) and ports (LP) for incorporation into frequency domain vector finite element method (VFEM) are described. LE and LP models are associated with a straight line or rectangle, containing arbitrary number of finite elements (FE) edges or faces. A proposed algorithm of incorporating lumped elements into VFEM mesh preserves global matrix symmetry and is compatible with model order reduction (MOR) technique. Numerical results confirm high accuracy and efficiency of the presented algorithms.
