Interactive graphical and visual examples of controlled experiments allow students to solve problems, make demonstrations, carry out measurements and other practical and theoretical activities. Iber is a two-dimensional numerical model used for simulating surface flow that combines hydrodynamic, turbulence, sediment transport and water quality modules, using the finite volume method to solve the corresponding equations. Its friendly interface for pre- and post-processing allows users to create videos of the results and to visualize 3D variables, and thus represents a robust, free, relatively easy-to-use, practical and effective teaching tool for hydraulic and hydrodynamic modeling. In this paper, we shall present several numerical examples of flow simulation in free shell, which can serve as complements to experimental teaching practices that, in many institutions, could be difficult to carry out because of economic and human resources constraints, or due to excessive assembly and operation time. The results illustrate the significant time saving achieved using the IBER model, compared to the laborious and unavoidable iterative calculations of the numerous equations; additionally, the versatility to enter, correct and visualize data is a great advance to the way of tabulating and presenting the results in a real practice. Simulation times are also very reasonable and depend on the type of problem, calculation method, numerical scheme or results to be obtained, and all these aspects can be easily modified during class sessions.
