Objective of this contribution is to show how to implement the Mild Slope Equations with Comsol Multiphysics. These equations are commonly used to study the propagation of waves in harbors. Some interesting features are presented, namely the use of weak terms (used for the modelling of the source); the evaluation of a smooth phase gradient from the complex dependent variable; a robust method to solve the wave dispersion relation with sufficient accuracy and continuity. As example application, the wave field that would occur in Casal Borsetti Marina (RA) in presence of a fictitious northward extension of the actual pears is shown.

Abstract
Objective of this contribution is to show how to implement the Mild Slope Equations with Comsol Multiphysics. These equations are commonly used to study the propagation of waves in harbors. Some interesting features are presented, namely the use of weak terms (used for the modelling of the source); the evaluation of a smooth phase gradient from the complex dependent variable; a robust method to solve the wave dispersion relation with sufficient accuracy and continuity. As example application, the wave field that would occur in Casal Borsetti Marina (RA) in presence of a fictitious northward extension of the actual pears is shown.File in questo prodotto:
