Portable F90 Source Code Version Now Free

The source code version is now free, just fill out and send the form below requesting it.   Or write me directly, at (alternate e-mail:  The source code version should work with any Fortran90 compiler. 


IMPORTANT:  The source code version is primarily intended for UNIX systems---Windows users should use one of the free Windows versions.   The source code is only useful for Windows users to recompile the library if the precompiled version is not compatible with your Fortran90 compiler.


The book  "Solving Partial Differential Equation Applications with PDE2D," G.Sewell, John Wiley & Sons, 2018 is the reference book for PDE2D.  The e-book has color, which is important for many figures, and here is the page.  The book examples can be downloaded from the book home page here, where videos for each chapter can also be viewed.

A book purchase is no longer required for the free versions, however.
