GeoDict User Guide 2025

Options

At the top left of the dialog, the name for the file containing the generation results can be entered in the Result File Name (*.gdr) box. The default name can be kept, or a new name can be chosen, fitting the current project.

The result files are saved in the chosen project folder (File Choose Project Folder, in the Menu bar). If a GeoDict result file (*.gdr) with the given name already exists in the project folder, a warning message is shown at the start of the creation process. You can either decide to rename the chosen file name to a new one, to cancel the generation process, to overwrite or to back up the old file. When nothing is selected, GeoDict uses the Back-Up option after a waiting time.

The available units (m, cm, mm, µm, nm and Inch) are selectable from the pull-down menu at the top right of the dialog. When the units are changed, the entered values are adjusted automatically.

GrainGeo_Create_OptionsDialog

The parameters are organized into tabs:

  • Create Options
    Determine general properties of the resulting structure, such as size, position, resolution, and solid volume fraction.
  • Object Options
    Define the geometrical properties of individual object types such as cross-section, length, and orientation. Up to eight different object types can be used in one structure.
  • Object Overlap
    Define how the IDs of different materials and objects are assigned. This is relevant for overlap operations performed on the structure and to define different materials with respective properties in the structure.
  • Result Options
    Determine if intermediate geometries are saved.

Different Create Grains Presets

In the bottom of the dialog find several helpful options.

The built-in default icon comes with a selection of different presets. Clicking on the little arrow shows several additional preset options.

The usual built-in default settings will load the settings according to the current GeoDict edition. You can change the current GeoDict edition from the Settings menu as described in the Graphical User Interface chapter.

In GrainGeo Create find the presets Electrochemistry and Oil and Gas. Choose the presets and inspect the entered parameters in the different tabs if they are a better base for your applications. For the Oil and Gas preset only the materials are changed. For the Electrochemistry version also domain, object and overlap parameters are changed.
