I’ve often used similitude requirements to argue for the use of real-time hybrid simulation in fluid-structure interaction experiments. Wave basin and flume experiments are, often by necessity, scaled due to the size and capacity limitations of the facility. This often results in small-scale structural models. There are three types of similitude: geometric, kinematic, and dynamic.…

I recently attended a joint workshop on the analysis, design, and testing of wave-energy converters (WECs) by the Pacific Marine Energy Institute (PMEC), Sandia National Labs, and OSU. A quote during one of opening presentations caught my attention: “It is estimated that if 0.2% of the ocean’s untapped energy could be harnessed, it could provide…

Hello again! This second set of Python video tutorials demonstrates how to plot a sinusoidal function. Although the concept is simple, the tools used in this example can be extrapolated to many other programming applications. It is one of the first examples given in my structural dynamics class, but many of the underlying concepts are…
