  Multiscale Finite Element Methods (MsFEM) are finite element type approaches
dedicated to multiscale problems. They first compute local, oscillatory,
problem-dependent basis functions which generate a specific discretization
space, and next perform a Galerkin approximation of the problem on that space.
We investigate here how these approaches can be implemented in a non-intrusive
way, in order to facilitate their dissemination within industrial codes or non
academic environments.
