Analyze and plot property simulation results

The results of GeoDict simulations with SatuDictPoroDictFlowDictFilterDict, and MatDict can not only be studied in detail using the visualization options of the modules, but also evaluated using the GeoDexcel Add-In included in the GeoDict package. 

GeoDexcel allows a deeper analysis of the numerical solver results and generating a variety of charts to graphically characterize structure properties. GeoDexcel automatically loads the result files data in the adequate form into the spreadsheet. The chart type selected by the user is created with GeoDexcel by automatically locating and loading the necessary data among the cells in the spreadsheet.

GeoDexcelTo use GeoDexcel, Microsoft Excel™ (version 2007 or newer) must be installed on the computer.

For the Dict modules, GeoDexcel offers the following analysis and charting:

  • FilterDict: filtration efficiency charts, particle deposition charts, and charts showing the pressure drop evolution during a filter lifetime simulation.

  • FlowDict: combination of results from different flow experiments and then, for comparison, plot the average flow velocity in the selected flow direction for all of them.

  • MatDict: plotting of the solid volume fraction (SVF), and components analysis. 

  • PoroDict: plotting of Through Pores, the cumulative geometric PSD and the density of geometric PSD.

  • SatuDict: output of capillary pressure curves, the relative conductivity and relative diffusivity charts, and the permeability chart for the non-wetting and the wetting phases.



Script command sequences to automate time-consuming, routine parameter studies

GeoDict offers the key possibility of recording, editing, and executing scripts prescribing a sequence of actions, even from different GeoDict modules, called macros.

Macros offer the advantage of:

  • automating sequences of operations

    1. without intermediate user interaction
    2. with automatic parameter variation

  • eliminating the error-prone and time-consuming sequential introduction of values, and clicking of buttons, for frequently repeated processes

  • documenting and allowing editing of input parameters

  • using Record to optionally postpone the execution of sequences of operations for complex parameter studies.

  • modifying an isolated parameter in a recorded macro using any text editor

  • executing the script without the graphical user interface (GUI), simply as a command line tool

The recorded GeoDict macro file (.gmc) in may encompass the information of .gdt and .gad (analytic data) files for the structure, of the images files (.png), and of generator- and solver-settings files.
