4 - 15   FVCOM Loader

The FVCOM Loader allows you to import netCDF files output from FVCOM into Tecplot 360 EX. Currently, classic netCDF and netCDF-4 formats are supported. The loader imports one or more FVCOM history outputs with the same topology and variable structure into a single Tecplot dataset, creating one zone for each time step. FVCOM history outputs with differing topology or variable structure can be combined but only through appending.

The X and Y grid variables are loaded directly from the file and projected to each Z position, which is derived from the zeta, h and siglev variables. The grid variables are chosen based upon the Coordinate System specified in the FVCOM attribute data. If no Coordinate System is provided, Cartesian is assumed.

The following auxiliary data is added to the data by the loader:

Auxiliary Name

Cartesian

Spherical

Common.XVar

Number of variable "x"

Number of variable "lon"

Common.YVar

Number of variable "y"

Number of variable "lat"

Common.ZVar

Number of variable "z"

Number of variable "z"

The vertical level and layer variables are added for visualization of FVCOM model layers. FVCOM variables stored at the nodes of each sigma level are loaded as nodal variables and variables stored at the elements for each sigma layer are loaded as cell-centered variables. FVCOM variables stored at the nodes of each sigma layer are interpolated to the volume cell-centers ignoring any FVCOM specified boundary conditions. Variables located at the elements of each sigma level are ignored. Attributes for the file and each variable are loaded into dataset and variable auxiliary data respectively.
