Hivel2D users manual
1 Introduction
Background
HIVEL2D is a free-surface, depth-averaged, two-dimensional model designed
specifically for flow fields that contain supercritical and subcritical regimes as well as the
transitions between the regimes. The model provides numerically stable solutions of
advection-dominated flow fields containing shocks such as oblique standing waves and
hydraulic jumps.
HIVEL2D has been verified by comparing computed model results with laboratory
data. The findings of these tests are presented in Stockstill and Berger (1994).
Purpose and Scope
This report serves as a user's manual for HIVEL2D Version 2.0. This user friendly
version of the program has been incorporated into SMS (Brigham Young University,
1997). First, a brief description of the model equations are presented. Next, step-by-step
instructions are given to guide the user in creating the required input files. These input
files include the geometry (numerical model computational mesh) file, the hydrodynamic
parameters/boundary conditions file, and the initial conditions file. Finally, the numerical
model output file is explained. Appendix A describes the file formats. Appendix B
describes the boundary conditions. Appendix C describes problems with the model and
solutions. Appendix D gives an example problem. Appendix E discusses the interpolation
program.
