Discontinuous Galerkin Methods for Spectral Wave/Circulation Modeling
Location:Dean’s Boardroom, 258 Fitzpatrick Hall
The interaction between waves and currents can lead to a 35 percent increase in water levels in the Gulf of Mexico during a hurricane event. This talk begins with the implementation of a new numerical modeling approach using a discontinuous-Galerkin method in both geographic and spectral space for a spectral wave model. This allows us to have an unstructured-triangulation in geographic space and a structured spectral space with the ability to use higher-order approximations when needed. We verify and validate the model on test bed cases and achieve higher accuracy when using higher-orders in spectral space. We then conclude with a discussion and results of coupling the spectral wave model to a discontinuous-Galerkin circulation model.
