Description	MOFAT is an upstream-weighted finite element model to simulate coupled flow of water, nonaqueous phase liquid (NAPL) and air, and multicomponent transport of up to five non-inert species in a 2D vertical section through saturated and unsaturated zones in Cartesian or radial coordinates. The flow module can be used to simulate a 2- or 3-phase system with gas phase treated dynamically or assumed at constant pressure. All flow simulations can be performed using either van Genuchten or Brooks-Corey soil properties. The program is dimensioned to handle 1500 nodes with 10 different material properties, 50 type-1 boundary nodes and 100 flux-type boundary elements, and 25 boundary condition cycles with 4 subcycles per cycle. A maximum of two seepage faces are allowed with a maximum of 50 nodes along any seepage face for a given phase. Convective-dispersive transport in water, NAPL and gas phase is analyzed assuming local equilibrium partitioning among phases and with the solid phase. It comes with pre- and post-processing capabilities. Only rectangular elements with sides parallel to the principle flow axes are permitted.
