Applications

This page is for selected links to source code for or descriptions of applications written in Fortran. These might be examples of contemporary “real-world” programs, or educational older codes. There are thousands of currently active examples across the sciences.

See Software repositories for collections of libraries and see Library distribution for methods for packaging and distributing Fortran libraries.

Condensed Matter Physics

GENEUS is an open-source Fortran 2008 program for simulating superconductor/ferromagnet nanostructures. It is based on the Usadel quantum diffusion equation, and supports nonequilibrium calculations, self-consistent calculations, and uses convergence acceleration algorithms to remain fast for tricky problems.

Astronomy

Interpreters and compilers

Interlisp

PL/M Compiler. Fortran IV code that does compile using gfortran. PL/M is the language that CP/M was written in (see http://www.cpm.z80.de/source.html for more details).

Nuclear

“The VCU nuclear reactor simulator, Richmond Pile 3, is a classroom and research tool that emulates a large commercial pressurized water reactor (PWR).” It uses gtk-fortran.
