# FreeFem++ sources

FreeFem++ is a partial differential equation solver for non-linear multi-physics systems in 2D and 3D

Problems involving partial differential equations from several branches of physics such as fluid-structure interactions require interpolations of data on several meshes and their manipulation within one program.

FreeFem++ includes a fast interpolation algorithm and a language for the manipulation of data on multiple meshes.

FreeFem++ is written in C++ and the FreeFem++ language is a C++ idiom.

## For users

The user documentation is available [here](https://github.com/FreeFem/FreeFem-doc) in Web format, or [here](https://github.com/FreeFem/FreeFem-doc-pdf/raw/master/freefem%2B%2Bdoc.pdf) in PDF format.

## For developers

All development take place in the develop branch (or in feature branches: cmake, geneo4PETSc, ... for specific projects)
