MaFloT is a Matlab based 2D Finite-Volume algorithm to simulate flow and transport in porous media. It was designed as a reference code at the Institute of Geophysics (now part of the Institute of Earth Sciences) at the University of Lausanne to evaluate multiscale algorithms. It can be downloaded free from this webpage. A detailed explanation of the package and the input-file can be found on the INTRODUCTION page. In addition MaFloTT, a two-phase flow package including gravity and capillary pressure effects is also downloadable from this webpage. Both codes are subject to the conditions of GPL license.
