anomod(1) U.S. Geological Survey (wrdapp) anomod(1) 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. 7 Jul 1998 1 anomod(1) U.S. Geological Survey (wrdapp) anomod(1) 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.
