Abstract
This letter proposes a novel projection technique for accelerating Finite Element Method simulations. The algorithm is based on the Second-order Arnoldi Method for Passive Order Reduction (SAPOR). It involves generation of two projection bases and thanks to this it is applicable to the systems of equations, which contain the quadratic frequency-dependence in the input term, that arise when projection is applied locally in the selected subregions of the computational domain. Numerical experiments show, that the proposed approach can be used to generate local macromodels, which are reliable for the wide frequency band simulations.
