PDE2D, the "sequel" to Visual Numerics' PDE/PROTRAN, solves quite
general nonlinear, time-dependent, steady-state and eigenvalue systems
of partial differential equations, in 1D intervals, general 2D regions
and a wide range of simple 3D regions.

or your own graphics programs
Trial Version
A trial version of PDE2D is available for multiple platforms:
Complete the PDE2D Trial Download form to access any trial version.
To preview screenshots of the PDE2D GUI, download guiex1.pdf (320 KB) , guiex2.pdf (488 KB)
In addition to the trial version, you can email Dr. Sewell (sewell@math.utep.edu) a complete "mathematical" (not physical) description of a PDE problem of interest to you, with typical values for all parameters. Dr. Sewell will be glad to set it up and attempt to solve it using PDE2D, and send you the results. If you want, you can also send the program resulting from a first attempt to set it up via an interactive or GUI session, but that is not required.
Description
PDE2D features an interactive user interface for solving general
nonlinear, time-dependent, steady-state and eigenvalue systems of
partial differential equations. The user only has to answer a series
of interactive questions about the region, partial differential
equations, and boundary conditions before selecting a solution method
and output options.
PDE2D provides a choice between a Galerkin method and a collocation
method for one-dimensional and two-dimensional problems, and a collocation
finite element method, with cubic Hermite basis functions, is used
for 3D problems.
A PDE2D program is created interactively. The interactive
driver automatically writes a FORTRAN program, based on the user's
answers, which is then compiled to create an executable program.
The questions are worded to reflect the number and names of the
unknowns, the type of system, and other information supplied in
answers to previous questions. For example, if a single linear steady-state
problem is solved the user will not be bothered with information
or options relevant only to time-dependent or nonlinear problems.
Extensive error checking is done during the interactive session.
System Requirements
The PDE2D interactive driver automatically creates a FORTRAN
program that is then compiled using a FORTRAN compiler, and linked
with the PDE2D library. A compatible FORTRAN compiler is thus
a prerequisite for PDE2D. Available hardware/OS/compiler combinations
are listed in Pricing and Ordering
Information.
