Equations (PDE) easily.
Problems involving PDE 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 quadtree-based interpolation algorithm and a language
for the manipulation of these data on multiple meshes. It contains
also a powerful mesh generation and adaption tool integrated
seamlessly in FreeFem++ called bamg.
FreeFem++ is written in C++ and the FreeFem++ language is a C++ idiom
allowing for a smooth learning curve.
