"FVCOM is a prognostic, unstructured-grid,
finite-volume, free-surface, 3-D primitive equation coastal ocean
circulation model developed by UMASSD-WHOI joint efforts. The model
consists of momentum, continuity, temperature, salinity and density
equations and is closed physically and mathematically using turbulence
closure submodels. The horizontal grid is comprised of unstructured
triangular cells and the irregular bottom is preseented using
generalized terrain-following coordinates. The General Ocean Turbulent
Model (GOTM) developed by Burchard’s research group in Germany
(Burchard, 2002) has been added to FVCOM to provide optional vertical
turbulent closure schemes. FVCOM is solved numerically by a second-order
accurate discrete flux calculation in the integral form of the
governing equations over an unstructured triangular grid. This approach
combines the best features of finite-element methods (grid flexibility)
and finite-difference methods (numerical efficiency and code simplicity)
and provides a much better numerical representation of both local and
global momentum, mass, salt, heat, and tracer conservation. The ability
of FVCOM to accurately solve scalar conservation equations in addition
to the topological flexibility provided by unstructured meshes and the
simplicity of the coding structure has make FVCOM ideally suited for
many coastal and interdisciplinary scientific applications.
FVCOM was originally developed for the estuarine
flooding/drying process in estuaries and the tidal-, buoyancy- and
wind-driven circulation in the coastal region featured with complex
irregular geometry and steep bottom topography. This model has been
upgraded to the spherical coordinate system for basin and global
applications. A non-hydrostatic version of FVCOM has been coded and is
being tested.
FVCOM is an open source code ocean community model that always welcomes
new users. This program is only permitted for use in non-commercial
academic research and education. Users are required to register in orde
to receive the source codes, demo examples, and user manuals as well as
some recommended postprocessing tools."
