Abstract
The simulation of multi-phase compositional problems requires the numerical solution of the advection - dispersion equation. Until now the main difficulties were: (1) the mixed types of equation (parabolic and hyperbolic) and (2) the limits in block size and time steps (grid PECLET number, COURANT number). In this paper a new algorithm (named the FRONT LlMITATION) is demonstrated which avoids most of the difficulties.
