Freetwm: a simulation tool for semiconductor lasers (J.Javaloyes et al).. Freetwm is a free (GPL) software designed for the study of the dynamics of multisection semiconductor lasers based on the Traveling Wave approach of Maxwell Bloch equations. Distributed Bragg gratings (possibly chirped), saturable absorbers and passive sections can be included. Parametric modulation of the bias current or of the reverse voltage as well as external optical injection can be achieved with arbitrary waveforms. At last, the (optional) mapping of the dynamics onto a simplified ensemble of coupled delayed equations allows for orders of magnitude speed improvements. https://onl.uib.eu/Softwares/
Simflowny: Simflowny has been fully developed by the members of the IAC3 group. This framework allows for the simulations of Partial Differential Equations, such as Navier-Stokes and Maxwell Equations or the Brusselator model. It can simulate Balance Law PDEs, Generic PDEs, Spatial Agent-Based Models such as Ising and Collective Motion (flocking) models as well as Graph-based Models, such as the Voter model and the Elementary Cellular Automaton. Simflowny can be downloaded and used as a docker container. Its source code is available from Bitbucket.
