Summary of ANOMOD

       anomod - FESWMS-2DH utility program to analyze simulation output

       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.

       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.

       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.

       ANOMOD creates graphic output files in HPGL format and tabular
       reports of FLOMOD simulation results.  The following options are

          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.

       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.
