NAME
anomod - FESWMS-2DH utility program to analyze simulation output
ABSTRACT
ANOMOD is part of a modular set of computer programs (FESWMS-2DH)
that simulates two-dimensional, depth-integrated, surface-water
flows. FESWMS-2DH consists of an input data preparation program
(DINMOD), flow model (FLOMOD), simulation output analysis program
(ANOMOD), and graphics conversion program (HPPLOT). 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.
ANOMOD presents the results of flow simulations graphically and in
the form of reports. Plots of velocity and unit-flow vectors;
ground-surface and water-surface elevation contours; and time-
history graphs of velocity, unit flow, or stage (water-surface
elevation) at a computation point can be produced. As such, ANOMOD
acts as a postprocessor in the FESWMS-2DH modeling system.
HISTORY
Version 1.10.DG1 06/03/92 - Converted to run on Data General AViiON.
Version 1.10 01/18/89 - FHWA official version; general code cleanup
and bug fixes.
Version 1.01 01/06/88 - Added option to plot contour line values.
Version 1.00 01/01/88 - Initial version developed for the Federal
Highway Administration, Offices of Research, Development, and
Technology, by the U.S. Geological Survey.
DATA REQUIREMENTS
ANOMOD begins by reading job control data records. Input data files
are read next if requested. Network data records and flow data
records are read next and will override information previously read
from an input data file.
OUTPUT OPTIONS
ANOMOD creates graphic output files in HPGL format and tabular
reports of FLOMOD simulation results. The following options are
available:
o Prints finite element network data (node & element data).
o Prints flow data (velocities in the x and y directions, water
depth, and water-surface elevation).
o Plots a finite element network.
o Plots velocity or unit flow vectors.
o Plots ground-surface elevation contours.
o Plots water-surface-elevation contours.
o Plots flow-check lines.
o Prints a time-history report of velocity, unit flow, and stage
(water-surface elevation).
o Plots time-history graphs of velocity, unit flow, or
water-surface elevation at a node point.
o Plots contours of the difference between water-surface
elevations produced by two different simulations. The function
can be used to plot contours of backwater caused by a bridge.
o Plots ground-surface elevation, water-surface elevation,
velocity or unit flow at a cross section.
o Checks all node and element numbers, time-history node numbers,
the number of flow-check lines, and the number of element sides
for compatibility with appropriate array dimensions and other
program limits.
SYSTEM REQUIREMENTS
ANOMOD 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.
