The LibMultiScale is a C++ parallel framework for the multiscale
coupling methods dedicated to material simulations. This framework
provides an API which makes it possible to program coupled simulations
and integration of already existing codes.
This Project is done in a collaboration between
EPFL within ENAC-LSMS (http://lsms.epfl.ch/) and
INRIA Bordeaux, ScAlApplix (http://www.labri.fr/projet/scalapplix/).
