FORTRAN Program (RELAX3D) to Solve the 3 Dimensional Poisson (Laplace) Equation

摘要

RELAX3D is an efficient, user friendly, interactive FORTRAN program which solves the Poisson (Laplace) equation lambda exp 2 =p for a general 3 dimensional geometry consisting of Dirichlet and Neumann boundaries approximated to lie on a regular 3 dimensional mesh. The finite difference equations at these nodes are solved using a successive point-iterative over-relaxation method. A menu of commands, supplemented by HELP facility, controls the dynamic loading of the subroutine describing the problem case, the iterations to converge to a solution, and the contour plotting of any desired slices, etc. (Atomindex citation 16:075703)
