3-D Finite-Element Saturated-Unsaturated Groundwater Flow Model

3DFEMFAT is a 3-Dimensional Finite-Element Model of Flow And Transport through Saturated-Unsaturated Media. A Preprocessor (for grid generation) and Postprocessor (for visualization) using GMS (FEMWATER Module required) are now included.  3DFEMFAT can do simulations of flow only, transport only, combined sequential flow and transport, or coupled density-dependent flow and transport. In comparison to conventional finite-element or finite-difference models, the transport module of 3DFEMFAT offers several advantages: (1) it completely  eliminates numerical oscillation due to advection terms, (2) it can be applied to  mesh Peclet number ranging from 0 to infinity, (3) it can use very large time step  size to greatly reduce numerical diffusion, and (4) the hybrid Lagrangian-Eulerian finite-element approach is always superior to and will never be worse than its corresponding upstream finite-element or finite-difference method. Because of these  advantages, 3DFEMFAT is ideal for applications to large field problems. The special features of 3DFEMFAT are its flexibility and versatility in modeling a wide range of  real-world problems. For 3-D finite-element saturated-unsaturated groundwater flow modeling, 3DFEMFAT is the model of choice.
