The DIMR-software is used to run a SOBEK 3 model in Delft-FEWS. In the General Adapter of Delft-FEWS we refer to the different components of the dimr-tool. This wiki will describe what you need to do to convert a SOBEK3 model to a dimr-model and how to set-up the different components of your Delft-FEWS configuration. Read the steps in this guide to implement your SOBEK 3 model in Delft-FEWS using the dimr-software.

DIMR Modules folder?

The Delft-FEWS DIMR-adapter requires a fixed folder structure:

...

The folders Input and Logs will be filled when you run the model. 

Make Delft-FEWS configuration files to run the model.

Step 5: create the ModuleDataSetFiles

Delft-FEWS can distribute model files to FSS machines. It is recommended to zip the model files and put it in the Delft-FEWS configuration.

  • In the Config\ModuleDataSetFiles create a zip file for the (update) model run. In our example the name for this zip file is Walrus_Hydr_Sobek3_Update.zip
  • The zip file for the ModuleDataSetFile contains the following information:
    • .\dlfow1d\.*.
    • .\rtc\.*.
    • ovd_dv.xml
  • As you might have notice this is the content of the dimr_model file that was created in step 1B.

How to generate ColdStateFiles?

Info
titleColdStateFiles

Delft-FEWS will need a state file to be able to run the SOBEK model. In order to generate the first state files of the SOBEK model it is recommended to do a stand-alone run of the DIMR/SOBEK from the command line. 

  • Go to FEWS_YourSystem / Modules / NewFolder / dimr_model / dflow1d and open

...

  • the flow model 1d.md1d

...

  •  file.
  • Go to option WriteRestart and make sure to set this setting on true. The model will now generate its state files.

  • The SOBEK 3 model has default timeseries. We can thus do a stand-alone run of the model without providing the model with data.
  • Open your command line window from the dimr_model folder. This is your working directory. Run the run_dimr.bat and give the dimr_config file as an argument. This file was created in step 1B. In the example below this is the ovd_dv.xml file.
  • Run the model.

  • After the model has run succesfully it is possible to craete a state-file for Delft-FEWS.
  • In the Config\ColdStateFiles\ create a zip for the cold state files. In our example this is the Walrus_Hydr_Sobek3_Update Default.zip
  • The zip file for the ColdState files contains the following information
    • Walrus_Hydr_Sobek3_Update Default \ dflow1d \ sobek.rda
    • Walrus_Hydr_Sobek3_Update Default \ dflow1d \ sobek.rdf
    • Walrus_Hydr_Sobek3_Update Default \ rtc \ state_import.xml
  • When you analyse the model results you will find a sobek.nda and sobek.ndf file in

...

  • the dimr_model \ dflow1d

...

  •  folder and a state_export.xml in

...

  • the dimr_model \ rtc

...

  •  folder. You can use these files. Make sure to rename the extension of these files.

What information should I put in the ModuleDataSetFiles?

    • ovd_dv.xml
  • As you might have notice this is the content of the dimr_model file created previously.
