Abstract
Visual examples and interactive graphs of controlled experiments allow the student to solve problems, demonstrate, measure, and do other practical and theoretical activities. Iber is a two-dimensional numerical model for simulating surface flow that combines modules of hydrodynamics, turbulence, sediment transport, and water quality, using the finite volume method to solve the corresponding equations. Its friendly interface for pre and post processing allows creating videos with results and displaying variables in 3D, making it a robust, free, relatively easy to use, practical and effective didactic teaching tool for hydraulic and hydrodynamic modeling. In this paper, we present some numerical examples of free surface flow simulation as complements to the experimental teaching practices that are difficult in many institutions due to lack of financial and human resources, or due to excessive assembly and operation time. The results show considerable time saved compared to the laborious and inevitable iterative calculations of the numerous equations involved; the versatility to enter, correct and visualize data is a great advantage to tabulate and present results during simulations of “real life” practices. The simulation times are also very reasonable and are associated with the type of problem, calculation method, numeric scheme, and obtained results, aspects that can be easily modified during class sessions.
