Summary of FESWMS-2DH
NAME
feswms-2dh - Finite-element surface-water modeling system for two-
dimensional flow in the horizontal plane
ABSTRACT
FESWMS-2DH is a modular set of computer programs that simulates two-
dimensional, depth-integrated, surface-water flows. FESWMS-2DH
consists of an input data preparation program (DINMOD(1)), flow
model (FLOMOD(1)), simulation output analysis program (ANOMOD(1)),
and graphics conversion program (HPPLOT(1)). The programs have been
developed to analyze flow at bridge crossings where complicated
hydraulic conditions exist, although they may be applied to many
types of steady or unsteady flow problems. Shallow rivers, flood
plains, estuaries, and coastal seas are examples of surface-water
bodies in which flows may be essentially two-dimensional in the
horizontal plane.
SYSTEM REQUIREMENTS
FESWMS-2DH is written in Fortran 77 with the following extensions:
use of variable names longer than 6 characters, mixed character and
non-character variables in common blocks, use of explicit length
declarations (INTEGER*2, INTEGER*4, REAL*4), include files, and
reference to compiler-dependent system date and time routines.
Graphics are coded using Computer Associates' DISSPLA library
references. Generally, the program is easily installed on most
computer systems that have access to the DISSPLA graphics library or
if the graphics are disabled by the user modifying the code. The
code has been used on UNIX-based computers.
