FreeFem++ is a programming language and a software focused on solving partial differential equations using the finite element method.

FreeFem++ is written in C++ and developed and maintained by Université Pierre et Marie Curie and Laboratoire Jacques-Louis Lions.

It runs on Linux, Solaris, macOS and Microsoft Windows systems.

The first version was created in 1987 by Olivier Pironneau and was named MacFem (it only worked on Macintosh); PCFem appeared some time later.
