Catchwords

conversion of computational grids
read and write computational grids in different file formats

Short Description of Functionality

Program GRIRDCONVERT can be used to convert computational grids for different mathematical methods:

• between different file formats but identical structure of the computational grid,
• between different grid types and different file formats,
• refinement (factor 4) of an UNTRIM grid, as well as
• flattening of all sub grid scale bathymetry variations within all grid cells and along all edges.

Due to some specific properties of computational grids for mathematical methods the number of possible conversions remains naturally very limited. The grid will not be optimized automatically with respect to the specific requirements of the different mathematical models.

Input-Files

1. computational grid (input formats)

The following file formats are currently supported:

• delft3d.grd, delft3d.dep, delft3d.enc, delft3d.dry,
• delft3d.thd, delft3d.lwl, delft3d.ext as well as delft3d.bnd,
• gitter05.dat/bin,
• selafin,
• untrim_grid.dat,
• utrsub_grid.dat,
• pltsub_grid.upi, and
• location_grid.dat.

Output-Files

1. computational grid (output formats)

The following file formats are currently supported:

• gitter05.dat/bin,
• untrim_grid.dat,
• utrsub_grid.dat,
• pltsub_grid.upi, and
• cf-netcdf.nc (actual only gitter05.dat/bin and location grid file).

Methodology

The computational grid informations are converted using various methods from the software package H_GRID as well as written to file in different formats.
Files with informations concerning locations are converted by the software package called L_GRID.

Notice: You can add some optional information blocks to the input file. This is the way to put additional meta data, e.g. of the CF-convention, into the CF-NetCDF file.

$PROGHOME/examples/gridconvert/data/loc/lg.allCFinfo.dat or
