The General Curvilinear Ocean Model (GCOM) uses a 3-D time-dependent curvilinear ocean model to simulate stratified ocean currents over uneven terrains with irregular bottom topographies in a rotating system. GCOM solves fluid flow dynamics for open oceans or coasts, lakes, bays, and estuaries. A parallel, componentized version of CGOM is being developed that that will utilize resources and services made available via distributed cyberinfrastructure environments and computational services, all interfaced with a user portal.
