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">
