...Although the code is primarily intended for investigations of fiber links, fiber amplifiers and fiber lasers, it can be applied to any other setting for which the governing equiations are valid. The physics included in the code is based on a generalized nonlinear Schrödinger equation, including higher order dispersion, stimulated Raman effect, gain with bandwidth limitation and saturation, loss, and saturable absorption. Disclaimer: The simulation code is provided free of charge for the use of the academic community only. We kindly ask the users to acknowledge use of the code in academic settings. ...

The program Orthos is developed to performed simulation (including nonlinear least-squares fitting) of EPR spectra of nitroxide biradicals. The program capabilities include simulation of rigid-limit and slow-motional spectra, of both isotropic and aligned samples. The spectra of multiple paramagnetic species, both bi- and monoradicals can be modeled. NB: Please note that now (as of Nov 2016) the distribution is being updated so that to improve reliability, OS-universality, and the quality of documentation. ...

Physical software, solves (3+1)D nonlinear parabolic equations. It simulates light propagation throw a continuous medium with saturable gain and absorption.

The Delta code is an nonlinear aeroelastic solver written in fortran 90. At the moment only vortex lattice aerodynamics is available but the hope is for a higher fidelity aerodynamic model to be developed for use in the current code. Linux and Unix.
