To import gridded output from Delft3D into FEWS, a grid definition needs to be specified in the FEWS grids.xml file. This grid file can be generated using the Matlab script print_Delft3D_grid.m attached to this WiKi.

6.2 State management

FEWS required to have a cold state file for each Delft3D model in the ColdStates folder (zipped). This cold state file is a Delft3D restart file which needs to be generated by the model developer up-front . This cold state file should contain (outside of FEWS), and needs to describe representative initial conditions.

The below configuration shows an example of the exportStateActivity to export a Delft3D model state from the FEWS generalAdapter.

 <exportStateActivity>
   <moduleInstanceId>DCSM_Historical</moduleInstanceId>
   <stateExportDir>%ROOT_DIR%/stateInput</stateExportDir>
   <stateConfigFile>%ROOT_DIR%/stateInput/export_states.xml</stateConfigFile>
   <stateLocations type="file">
      <stateLocation>
         <readLocation>dcsm98.res</readLocation>
         <writeLocation>dcsm98.res</writeLocation>
      </stateLocation>
   </stateLocations>
   <stateSelection>
      <warmState>
         <stateSearchPeriod unit="hour" start="-48" end="-1"/>
      </warmState>
   </stateSelection>
</exportStateActivity>

From the Delft3D-FLOW file this initial state file is subsequently called in the following way:

Commnt=
Restid= #dcsm98.rst#
Commnt=

Commnt=                              
Restid= #dcsm98.rst#
Commnt= 

The warmState search period should be sufficiently long to spin-up the model in case of a cold start.State files and names
