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.

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 sections
- Field intensity profiles
- Sparse LU decomposition (PARDISO from Intel MKL) used to solve
coupled infinite cylinders,
separated by 1 nm. |E|^2 is shown.

|ANNOUNCEMENT: jFEM and parts of jScience have
been rewritten from scratch, following coding standards
and utilizing C++ 11 functionalities. jFEM is also much
faster, and has been written to be user-friendly. These
codes will be distributed elsewhere, TBD.
