Physical Models and Demonstrations Based on two decades' experience as an engineering educator, Steve Ressler has found that many concepts in physics, mechanics, civil engineering, and mechanical engineering are most effectively illustrated through the use of physical models and demonstrations The Journal of Computational Engineering and Physical Modeling (CEPM) is an international open-access journal (online) published quarterly by Pouyan Press which was founded in 2017. Recent developments of experimental studies along with computational techniques lead to the comprehensive understanding of engineering phenomena 3.3 Physical Modelling. Designers use physical models to visualize information about the context that the model represents. It is very common for physical models of large objects to be scaled down and smaller objects scaled up for ease of visualization. The primary goal of physical modelling is to test aspects of a product against user. The facilities typically used for coastal physical modelling investigations include: 0.6 m wave flume. 1 m wave flume. 1.2 m wave flume. 3 m wave flume. Wave basin. All wave flumes and the wave basin can be operated with monochromatic or irregular waves, defined by spectral or time series wave parameters, or by a pre-recorded wave signal
