Web13. apr 2024 · Overtopping flow velocity (OFV) and overtopping layer thickness (OTL) are essential parameters in breakwater design. Several empirical equations to predict these parameters are available in many works of literature, but most of the equations were derived based on impermeable structures such as sea dikes. In this study, we experimented with … Web10. feb 2011 · The most general algorithm to simulate an electromagnetic wave in arbitrarily-shaped materials is the finite-difference time domain method (FDTD). It solves the wave equation, one time-step at a time, on a 3-D lattice. It is quite complicated to program yourself, though, and you are probably better off using a dedicated package such as Meep.
