solve boundary value problems over an unstructured mesh. FEM is particularly well suited for modeling domains of arbitrary shape, and efficiently modeling small features in large computational domains.

JFEM (2D/3D):
from which the electric field is calculated. In 3D, the vector wave equation is solved for the electric or magnetic field directly. - (2D) Triangular elements with first order nodal basis functions - (3D) Tetrahedral elements with 0, 1st, or 2nd order H0 curl interpolatory vector basis functions (constructed from Whitney edge elements) or H1 curl 1st order vector basis functions - Sommerfeld radiation condition imposed on exterior of computational domains (1st order) to model open--region scattering problems - (3D) Truncation of domains using a dielectric material - Absorption, scattering, and extinction cross section calculation - Output of field intensity profiles - Sparse LU decomposition (PARDISO from Intel MKL) to solve matrix equations
