General Curvilinear Coastal Ocean Model
The GCCOM model is capable of reproducing non-hydrostatic features such as the interaction of currents with steep bathymetric features at high resolutions.
Areas of Applications: Stratified and density driven flows, Hydrodynamic simulations, Thermal stratification in lakes, seas and reservoirs, Non-hydro-static flows:Internal Waves, Internal Tides, Internal Bores.
- Primitive 3D Navier-Stokes equations using Boussinesq approximation.
- Nondimensionalization and scaling of the NavierStokes equations.
- Large Eddie Simulation (LES).
- Fully written in FORTRAN 90.
- Uses General Curvilinear Coordinates.
- Using Fully Non-Hydrostatic Pressure Equation.
