NESC9722 FE3DGW.

1. NAME OR DESIGNATION OF PROGRAM:  FE3DGW.

3. DESCRIPTION OF PROGRAM OR FUNCTION

FE3DGW (Finite Element 3-Dimensional Ground Water) analyzes flow through large, multilayered, ground-water systems. The code has the capability to model noncontinuous as well as continuous layers, time-dependent and constant sources/sinks, and transient as well as steady-state flow.

4. METHOD OF SOLUTION:

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:

6. TYPICAL RUNNING TIME:

NEA-DB executed the test cases included in this package on a VAX-11/780 computer. The following times were required (in CPU  seconds):
                 EXAMPLE1(ABC)      46 (total)
                 EXAMPLE2           20
                 EXAMPLE3           21
                 EXAMPLE4           20
                 EXAMPLE5           27

7. UNUSUAL FEATURES OF THE PROGRAM

The code offers a wide choice of boundary conditions including prescribed heads, nodal injection or withdrawal, constant or spatially varying infiltration rates, and elemental source/sink. Initial conditions can be prescribed as vertically hydrostatic or variable hydraulic head. The heterogeneity in aquifer permeability can be described by geologic unit or explicitly for given elements. Three-dimensional elements are generated from user-defined well logs at each surface node. To facilitate interaction between disciplines, auxiliary programs are provided to plot the finite-element grid, well logs, contour maps of input and output parameters, and vertical cross sections and to determine ground-water pathlines and travel from a specified point.  FE3DGW does not account for density variation and calculates only the hydraulic heads. The program can be used to support site characterization, evaluate ground-water flow rates, and estimate travel path and time in regional and local ground-water systems.

8. RELATED AND AUXILIARY PROGRAMS

FE3DGW uses the proprietary CalComp and DISSPLA graphics software to generate graphical output.
