Catchwords

conversion of Delft3D computational results

Short Description of Functionality

The program GETDATA converts Delft3D computational results into the network Common Data Form netcdf.cdf. DATACONVERT offers the opportunity to convert these netCDF files in a further step into BDF files.

Input-Files

1. computational results in Delft3D map files

   Each dataset requires a data file trim-*.dat and a definition file trim-*.def. These files are

   also referred to as NEFIS files.

   NEFIS may include more than Delft3D results, but this description is restricted to the map

   files. For more information have a look in the Delft3D-FLOW-User Manual (see below), p. 6-7.

2. nefis.ini for initialisation
3. simetf
4. simona.cfg for configuration
5. simona.env for setting the environment;

Files 2 to 5 and the executable have to be located in the working directory. The batchfile copy_getdata.bat copies them there.

It is located in the search path. Use:

copy_getdata [working_directory], e.g. copy_getdata C:\temp

Output-Files

1. converted computational results as netcdf.cdf

This file differs from the netCDF files written by BAW software. This type can neither be loaded by the ArcGIS-GEI-Dataloader

nor by Davit

Methodology

• Reading the map files is done by methods of the NEFIS 5 library, whereas the netCDF library performs the NETCDF output. 3D results are in both formats stored in sigma layers.
• NEFIS 5 has overcome the 2 GB file size barrier. For large datasets it is recommended to convert the physical measures seperately, since the file size of the NETCDF files has become the new bottleneck.
• GETDATA requires two lines of console input. It is recommended to import them from a txt file,

e.g. from $PROGHOME/examples/getdata/getdata_input.txt.
