A CUDA Solver for Helmholtz Equation

摘要：

　　In this paper, we present a CUDA based solver for the Hehnholtz equation △u + λu =f in three dimensional rectangular area.This solver follows the algorithm of FISHPACK A Fortran package for solving elliptical equations.It uses DFT and its variants such as DST and DCT to efficiently find the numerical solution.It is able to solve five different kinds of boundary conditions for each coordinate direction.The experiments show that it can achieve a speedup of up to around 30 compared to the solver in FISHPACK.The source code can be downloaded from https://github.com/rmingming/cudahelmholtz/.
