Cactus Code Thorn WaveToy1DF77 Author(s) : Gabrielle Allen Maintainer(s): Cactus team Licence : LGPL -------------------------------------------------------------------------- 1. Purpose This thorn illustrates the solution of the scalar wave equation in 1D using centered explicit finite differencing. Included are routines to * Set up and register the 1D spatial coordinate system * Calculate initial data * Evolve using a standard explicit method The Cactus infrastructure used includes * Boundary conditions (CactusBase/Boundary) * Timestep calculation (CactusBase/Time) * Parallel driver (CactusPUGH/PUGH) * IO (Standard IO thorns)
