  2. PDE2D History • Work began 1974 in Caracas, Venezuela • Sold as TWODEPEP by IMSL, 1980-1984 • Sold as PDE/PROTRAN by IMSL, 1984-1991 • “Analysis of a Finite Element Method: PDE/PROTRAN,” Springer Verlag, 1985 • Sold as PDE2D by Granville Sewell, 1991-2007 • “The Numerical Solution of Ordinary and Partial Differential Equations, second edition” John Wiley & Sons, 2005 • Sold as PDE2D by VNI/Rogue Wave, 2007- • 2011: Free versions for Windows and Linux, for small to moderate size problems, now downloadable at www.roguewave.com/pde2d

  3. PDE2D User Interfaces • A GUI interface can be used to access the collocation (0D,1D,2D,3D) finite element methods • An Interactive Driver interface can be used to access the collocation and Galerkin (1D,2D) finite element methods • PDE2D produces its own graphics, but also automatically generates a MATLAB program to produce MATLAB graphics • PDE2D has all the flexibility of FORTRAN, for example, you can write FORTRAN functions to define any PDE or BC coefficients, or write your own postprocessing code
