Overview
Import Delft3D Flow model results that are stored in the NEFIS file format. There are 2 types of Delft3D Flow model results:
- Point-based output
- Grid-based output.
In both cases data are stored in NEFIS file but the structure is different.
Input from NEFIS
Currently the Delft3DFlow import can import point-based results only which are stored in a number of NEFIS structures (groups, cells, elements as they are defined in the NEFIS file format):

Configuration
To import location-based data from Delft3D Flow NEFIS file setup a TimeSeriesImport module configuration like:
<?xml version="1.0" encoding="UTF-8"?> <timeSeriesImportRun xmlns="http://www.wldelft.nl/fews" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.wldelft.nl/fews http://fews.wldelft.nl/schemas/version1.0/timeSeriesImportRun.xsd"> <import> <general> <importType>Delft3DFlow</importType> <folder>../junit_test_output/nl/wldelft/fews/system/plugin/dataImport/TimeSeriesImportTestData/import/delft3dflow</folder> <idMapId>delft3dflowMapId</idMapId> <importTimeZone><timeZoneOffset>+01:00</timeZoneOffset></importTimeZone> </general> <timeSeriesSet> <moduleInstanceId>ImportDelft3DFlow</moduleInstanceId> <valueType>scalar</valueType> <parameterId>Z.m</parameterId> <locationId>shepelevo</locationId> <timeSeriesType>external forecasting</timeSeriesType> <timeStep unit="minute" multiplier="1"/> <relativeViewPeriod unit="day" start="0" end="4"/> <readWriteMode>add originals</readWriteMode> </timeSeriesSet> </import> </timeSeriesImportRun>
