Absorbance Simulation of Gold Octahedra

[shinobi20]

I want to simulate the absorption spectra of gold octahedra when irradiated by a light source, according to the information I have gathered I can use discrete dipole approximation technique because octahedra is not spherical (in contrast to Mie Theory which is applicable to spherical particles). I also saw from some website that DDSCAT can run the discrete dipole approximation. I have no knowledge on programming or anything related to computers so I'm confused on what to do.

Fortran is always mentioned in those information and using some compilers, but I am lost.
