Computer software that implements the
BEM for Laplaces equation is described in this manual.
The codes can be directly downloaded.
The codes are written in Fortran 77 and it is
recommended that users have a working knowledge of this
programming language to obtain full benefit from the codes.
The are three main subroutines that deal with computing the
discrete Laplace operators in each dimensional space:
L2LC in file L2LC.FOR for general two-dimensional problems,
L3LC in file L3LC.FOR for general three-dimensional problems,
L3ALC in file L3ALC.FOR for general three-dimensional axisymmetric problems.
The methods employed in the codes and the way the way in which
they should be used is described in Chapter 3.
For each of the codes a test problem is implemented in which
the simple solution and Dirichlet boundary condition is
f(p) = p2 in two dimensions,|
with the Laplace equation governing the domain interior to
a closed boundary.
The main programs
L2LC_T (in file L2LC_T.FOR ) solves the
two-dimensional problem with the boundary a circle.
L3LC_T (in file L3LC_T.FOR ) solves the
three-dimensional problem with the boundary a cube.
L3ALC_T (in file
three-dimensional problem with the boundary a sphere.
Further details on the test problems and the results
are given in Chapter 3.
f(p) = p3 in three dimensions,|
These are the core codes. The codes for the
three problem domains are covered in subsequent chapters.
