An Unstructured Grid, Finite-Volume Coastal Ocean Model (FVCOM) System
Ocean Model (FVCOM) System Unstructured Gri
2015/7/23
The coastal ocean extends from the land-sea interface where freshwater enters the ocean through rivers and estuaries to beyond the continental shelf. Due in part to its shallow and complex bathymetry ...
An unstructured-grid, finite-volume, nonhydrostatic, parallel coastal ocean simulator
Nonhydrostatic Unstructured grid Parallel Internal gravity wave
2015/6/30
A finite-volume formulation is presented that solves the three-dimensional, nonhydrostatic Navier–Stokes equations with the Boussinesq approximation on an unstructured, staggered, z-level grid, with t...
