Note: {installfolder} refers to the full path of the directory you installed iMOD in (e.g. D:\iMOD).

The tutorials come with a Tutorial Data Set located in {installfolder} \tutorials; in this manual {installfolder} \tutorials refers to the full path of the sub-folder. \tutorials, see section 2.2. If the Tutorial Data Set subfolder . \tutorials is not present (anymore) on your computer, download it from oss.deltares.nl. and perform the following steps:

• 2. Double-click the archive iMOD_Tutorial_Data_Set_V5_1.exe, the following pop-up window appears:

• 3. In the pop-up window choose the destination-folder where you want to unzip the Tutorial Data Set: you can accept the default{installfolder} (e.g. D: \iMOD) by clicking the OK-button, or choose another location first; after clicking the OK-button the archive will be unzipped.

After the archive has finished self-extracting (it may take a while to extract more than 6600 files...) a new sub-folder tutorials has been created in the above chosen destination-folder.

Note: In this user manual {installfolder} \tutorials refers to the full path of the newly created tutorials-sub-folder, e.g. to D: \iMOD \tutorials.

The folder {installfolder} \tutorials contains a sub-folder for each individual tutorial:
