PDE2D, a general purpose finite element program, solves 1D, 2D and 3D PDEs
Free versions available for small to moderate size problems
PDE2D 9.4, originally based on VNI's 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.
PDE2D features a graphical user interface (GUI), and an interactive user interface, which make it exceptionally easy to use, and extensive graphical output capabilities. A Galerkin finite element method, with isoparametric triangular elements of up to 4th degree, is available for 2D problems, and a collocation finite element method, with cubic Hermite basis functions, is used for 3D problems. For 1D and 2D problems, both Galerkin and collocation algorithms are available. Adaptive refinement and grading of the triangular mesh are available for 2D problems.
试用版虽然限制了变量个数，但是，对大多数人论文涉及的问题，都还是绰绰有余的。
The trial versions include working versions of PDE2D 9.4 that can be used to solve small to moderate size problems, but not large problems.
For 1D problems there is a limit of 200 unknowns,
for 2D problems, 5,000 unknowns, and
3D problems are limited to 15,000 unknowns.
All of the 15 prepared Interactive Driver and 3 GUI examples will run with the trial versions.
If you do not have the required Fortran compiler, you can still run the Interactive Driver and GUI, and work through the prepared examples and see exactly what PDE2D can do and how easy it is to use.
After downloading, put the ZIP file in your top level (C:\) directory (Windows) or $HOME directory (Linux and Solaris), and unzip, then look for the README_DEMO file for further instructions. A Windows PostScript viewer, to view the PS files generated by PDE2D, is available here.
