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+.
Suggested add-ons: the ports graphics/xd3d, science/medit and math/gnuplot
(medit and gnuplot are requested to run some examples).
