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.

Features
Benefits
- Easy to use - Users do NOT need to be programmers!
- Eliminates the need to write code from scratch
- Offers all the speed of FORTRAN
- Provides all the flexibility of FORTRAN - Call library routines, modify a program or embed it in another application
- Displays results with built-in graphics, a MATLAB m-file or your own graphics programs
Trial Version
A trial version of PDE2D is available for multiple platforms:
To run the trial version, download one of the ZIP files below and unzip it in your TOP-LEVEL (Windows) or $HOME (Linux/Solaris) directory. Then look for the README.DEMO file for further instructions.
Technical support for PDE2D is available from the author of the product, Dr. Granville Sewell through a Visual Numerics Forum. Visit the PDE2D Forum: http://forums.vni.com/forumdisplay.php?f=26
View examples of using the PDE2D GUI
View example of 3D plot using a generated MATLAB program
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.
