PDETWO: Approximation of a PDE in 1 Time and 2 Space Dimensions
is a FORTRAN77 library which
approximates a time-dependent partial differential equation (PDE)
in two spatial dimensions.
The text of many ACM TOMS algorithms is available online
TOMS565 is available in
a FORTRAN77 version.
Related Data and Software:
a FORTRAN77 library which
approximates a 1D PDE as a system of ODE's;
this library is commonly called PDEONE;
this is ACM TOMS algorithm 494.

nonlinear partial differential equations,

Examples and Tests:
Problem 1 is a simple elliptic equation.
Problem 2 is the Burgers equation.
Problem 3 is a coupled system of PDE's. This problem currently
causes the time integrator to fail.
List of Routines:
PSETM generates the jacobian matrix.
PDETWO converts the user's PDE system into ODE's for the time integrator.
STRSET sets up storage.
DRIVEP is the driver program for the time integrator.
INTERP interpolates values of the dependent variable.
STIFFP takes one integration step.
COSET sets integration coefficients.
DECBR computes the LU decomposition of a banded matrix.
SOLBR solves a banded linear system.
PDB defines the jacobian if MITER = 1.
