We have proposed a new method to discretize kinetic equations. It is basedd on a discretization of the velocity variable which is local in time and space. This induces an important gain in term of memory storage and CPU time, at least for 1D problems (this work has been rpesented in a paper submitted for publication). Two-dimensional extensions are under development.
