Output - simulator input page

This is the Next >> page accessed in WizGen in Flexible project mode from the User-defined plugins page or by selecting the Goto... button for Specify simulator output options from the Contents page.

The primary purpose of TransGen is to calculate simulator include files which are representative of the properties and structure of the faults in the model. This page allows the user to specify the output of the calculation results generated by running the current TGDATA file via ViewGen to files suitable for inclusion in the parent model which will be one of the following:-
  • Eclipse simulator

  • MoReS simulator (for Shell users only)

  • MORE simulator (the Roxar Modular Oil Reservoir Evaluation simulator)


    • HINT:- You may not initially want to output any files until you have viewed and perhaps recalculated the fault properties via ViewGen.

    By default, the results that the ViewGen module of TransGen generates, are output to the graphical window., i.e. the Enable 3D graphics viewer after calculation option is toggled "on", as shown bottom left of the page. This is optional as ViewGen can be run as a batch process. The graphical output may be toggled on or off.  A green box and a tick is shown when graphical output is enabled:



    The file output is activated by inputting directory/filename target either by typing the full pathname/filename in the relevant box or by selecting the appropriate Browse... button to open a File selection window in which to navigate to the required OUTPUT directory and select/input output file name, as shown below for the Transmissibility data files editnnc.txt, tranx.txt and trany.txt.

    Directories can be selected by double-clicking with <MB1> in the Directories box ( the directory ending with two dots means go up a level).  Existing files can be selected by double-clicking with <MB1> in the Files box.  A new file can be created by appending a new filename to the existing (or reselected path in the Selection box).  Press OK to proceed, or Cancel to drop the changes.  This will return control to the Output page of WizGen.





    In the example shown above, the following Eclipse-format Transmissibility data files have been selected for output from TransGen (for subsequent inclusion in the Eclipse parent model):-

  • EDITNNC file - Transmissibility multipliers for all faulted non-neighbour connections

  • TRANX file - X-direction transmissibilities for all faulted neighbour connections

  • TRANY file - Y-direction transmissibilities for all faulted neighbour connections

  • NNC file - Transmissibilities for all faulted non-neighbour connections not in the original parent model, but generated via the new fault drag and hierarchical zone functionality.


    • NOTE:- The NNC file output option for the Eclipse simulator is new to the TransGen version 3.2 release. It is only relevant when including fault drag and sub-resolution fault zone effects in the simulation model, i.e. with the Include fault drag and hierarchical zone effects option toggled "on" via the Title page of WizGen in "Flexible project" mode. Otherwise the NCC output option will be "greyed-out" and unsettable.


    When the Output settings are saved to the TGDATA run file, they are added as strings below the TGRPT keyword, as shown below:-

    --<OUTPUTS+>
    TGRPT
    'EDITNNC=/output_directory/editnnc.txt'
    'TRANX=/output_directory/tranx.txt'
    'TRANY=/output_directory/trany.txt'
    'GRAPHICS'
    /
    --<OUTPUTS->

    With these Output settings, the graphical display will be activated when ViewGen is successfully run using the saved TGDATA file and the Transmissibility data will be exported to the files as specified to be input into the Eclipse model.

    When the Output - simulator input page is set as required, click on the Next >> button to view/edit the Output - derived and user-defined properties page.

    Alternatively, click on the << Back button to return to the User-defined plugins page.

    Or click on the Contents button to access the Contents page to view/edit any of the current WizGen page settings, inspect the current TGDATA file or the session log generated by last ViewGen calculation.

    Click on Save to save any modifications made to the current TGDATA runfile.
    Click on Quit to exit from WizGen with or without saving the any changes to the TGDATA runfile.
