Release 4.2.1. — 2019. — 661 p.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 its language is a C++ idiom.Learning by Examples
