CCHE2D is an integrated software package developed at the National Center for Computational Hydroscience and Engineering, the University of Mississippi. This model is based on Efficient Element Method. It is a general numerical model for two-dimensional
simulation and analyses of free surface flows and the associated processes. Water flows in rivers, lakes, reservoirs, and coasts including floods, dam break flows can be simulated by CCHE2D model. The processes of sediment transport, morphologic change, pollutant transport and water quality, etc. dominated by water flows can also be studied using this model.
A Graphic User Interface, CCHE-GUI, has been developed for applications of CCHE2D. The GUI is a user-friendly tool, it helps to setup parameters, boundary and initial conditions, drive and manage simulation cases, visualize, analyze and animate the simulation results. A mesh generator, CCHE-MESH, is also developed for effectively discretize a computational domain for numerical simulations.
In this short course, general methodologies of the models will be covered and test examples
will be used to demonstrate the use of the models. Several test cases will be used for hands-on practice of entire numerical simulation processes. The CCHE2D model is being continuously refined, enhanced and improved for better and additional capabilities at the NCCHE. New versions of the base model and the modules will be reported and released in the near future.
