|

|
! This sample program solves a linear system obtained by discretizing a
|
||||||
|
! PDE with Dirichlet BCs.
|
||||||
|
!
|
||||||
|
!
|
||||||
|
! The PDE is a general second order equation in 3d
|
||||||
|
!
|
||||||
|
! b1 dd(u) b2 dd(u) b3 dd(u) a1 d(u) a2 d(u) a3 d(u)
|
||||||
|
! - ------ - ------ - ------ - ----- - ------ - ------ + a4 u = 0
|
||||||
|
! dxdx dydy dzdz dx dy dz
|
||||||
|
!
|
||||||
|
! with Dirichlet boundary conditions, on the unit cube 0<=x,y,z<=1.
|
||||||
|
!
|
||||||
|
! Example taken from:
|
||||||
|
! C.T.Kelley
|
||||||
|
! Iterative Methods for Linear and Nonlinear Equations
|
||||||
|
! SIAM 1995
|
||||||
|
!
|
||||||
|
! In this sample program the index space of the discretized
|
||||||
|
! computational domain is first numbered sequentially in a standard way,
|
||||||
|
! then the corresponding vector is distributed according to a BLOCK
|
||||||
|
! data distribution.
|
||||||
|
!
|
||||||
|
! Boundary conditions are set in a very simple way, by adding
|
||||||
|
! equations of the form
|
||||||
|
!
|
||||||
|
! u(x,y) = exp(-x^2-y^2-z^2)
|
||||||
|
!
|
||||||
|
! Note that if a1=a2=a3=a4=0., the PDE is the well-known Laplace equation.
