Welcome to the Radiation Boundary Condition Package

The purpose of this library is to provide accurate and efficient radiation and absorbing boundary conditions to truncate the computational domain for the simulation of a variety of wave propagation problems in the time domain. The plan is for RBCPack to contain stand-alone components that implement complete radiation boundary conditions and/or double absorbing boundary layers for a variety of popular time-domain wave propagation solvers.

Components

Currently, the following components are available:

Yee/FDTD

This component provides complete radiation boundary conditions in the for of a double absorbing boundary for Yee/FDTD solvers.

Utilities

A collection of useful routines that may aid in the development of other boundary implementations.

Other components are under development and will be released as they are completed. Components to handle (un)structured discontinuous Galerkin methods and methods based on modified equations are nearing completion and should be released in the near future. Components for Hermite methods are in the early stages of development.

Downloading

The code is also hosted in a read only repository: RBCPack github reposistory. Alternatively, the current release of each component can be downloaded from their respective pages.

The code is released under the LGPL v3. See http://www.gnu.org/licenses/lgpl-3.0.en.html. If a different license is required, please contact us.
