Known issues

Unsolved in SOBEK 2.16 2D Grid causes simulation to stop without error due to Unix End of Line format

SOBEK requires 2D grids to have Windows End of Line format. Grids that have been created on Linux or with QGIS (for example), will need to be converted to the Windows format. If your GIS software does not provide an option to change this, or if you have received your grid from a third party, you can manually change the format as follows:

  • Download and install the free text editor Notepad++
  • Open your grid with Notepad++
  • In the menu, click on ‘Edit’ – ‘EOL Conversion’ – ‘Windows (CR LF)’
  • Save the grid and reopen your SOBEK model

Note: If the option to convert to Windows format is greyed out in Notepad++, your grid already uses the Windows format.
