TUCWave

Participant : Maria Kazolea [Corresponding member] .

TUCWave, developed within the PhD of M. Kazolea, is a high-order well-balanced unstructured finite volume (FV) solver for weakly nonlinear and weakly dispersive water waves over varying bathymetries, as described by the 2D depth-integrated extended Boussinesq equations of Nwogu (1993). The FV scheme numerically solves the conservative form of the equations following the median dual node-centered approach, for both the advective and dispersive part of the equations. The code uses an efficient edge based structure. For the advective fluxes Roe's approximate Riemann solver is used along with a well-balanced treatment of the topography source. Higher order accuracy i is achieved through a MUSCL-type reconstruction technique, and via a strong stability preserving explicit Runge-Kutta time stepping. The numerical techniques implemented in TUCWave are being imported in SLOWS.
