freeFem++

FreeFem++ is an implementation of a language dedicated to the finite element method. It provides you a way to solve Partial Differential Equations (PDE) simply. Problems involving partial differential equations (pde) of several branches of physics such as fluid-structure interactions require interpolations of data on several meshes and their manipulation within one program. In this report we build on a fast quadtree-based interpolation algorithm, propose a language for the manipulation of data on multiple meshes (generated with bamg) and test by designing an extension of freefem. and of freefem+. FreeFem++ is written in a C++ idioms, this software run on all unix OS (with g++ 2.95.2 or more and X11R6), on Window95, 98, 2000, NT, and on MacOS 9 and X (carbon version).
