Fault Controls

With Show faults toggled "on", click on the Fault controls... option in the ViewGen Edit menu to access the Fault Controls window.

This is the principal dialog box which controls the display of faults.  The Faults Columns/Rows/Layers list boxes,  the Imported Faults list box, the Property filter and the Always display ViewGen generated faults option settings, control which part of which faults will be displayed.  Apart from colours, the manner in which an active fault property is displayed is controlled by Fault Views box.  The operation of these are described below:

The active fault property is selected by the Fault Properties menu.
Fault colours are controlled by the Fault Colourmap editor.

The Fault Columns/Rows/Layers list boxes

These boxes allows a mouse-driven selection of faults that lie within selected regions of the model.  By default, the entire volume is selected (selected volumes are shown in the Fault cols, rows and layers lists by white text on a black background).   Only those fault faces indexed to cells lying in the selected region will be displayed.  Moving the scroll bar to the right of each list allows movement through the entire list.

To change the set of cells that are displayed:

All / None selects/deselects the entire list

Clicking with <MB1> on a single Row/Column/Layer selects a single item only from each of the lists.

Clicking with <MB1> on a single Row/Column/Layer, and then holding down shift and clicking on another Row/Column/Layer selects all Rows / Columns / Layers in that range.

Holding down the Control key and clicking with <MB1> selects /  deselects additional items from the lists.

Then press OK or Apply to update the display in the ViewGen window.

The Imported faults list box

This lists all the faults imported into TransGen from the Eclipse model (via the FAULTS keyword on the Included Data page in WizGen). Many fault faces may be associated with a single name by using the Eclipse FAULTS keyword in the input data. If Eclipse FAULTS data has not supplied or has not been included in the current TransGen project, this list will be empty.

HINT:- Even if FAULTS data are not included, ViewGen will find the faults by the offset of cell corners and these will be displayed with the Always display ViewGen generated faults option toggled "on" (default setting). Toggle this option "off" to visualise individual user-defined faults rather than the automatically generated "background" faults.


The Imported faults list allows mouse-driven selection of Eclipse faults by name.  By default, all the Imported faults are selected (shown by white text on a black background in the fault-name list).   Only those Imported faults that are selected will be displayed.  Moving the scroll bar to the right of each list allows movement through the entire list.

To change the set of Imported faults that are displayed:

All / None selects/deselects the entire list

Clicking with <MB1> on a fault name selects a single item from the list

Clicking with <MB1> on a single name, and then holding down shift and clicking on another name selects all names in that range.

Holding down the Contrlol key and clicking with <MB1> selects /  deselects additional items from the list.

Then press OK or Apply

Property filter

The Property filter selects where the active fault property will be displayed by value.  By default, the range is set to include the entire range of the fault property  (i.e. everywhere).  The range may be restricted to show values within a certain range, and then the Inclusive toggle button becomes active.  By default, the Inclusive option is toggled "on" - all values within the range are displayed. If toggled "off," the range becomes exclusive - only cells outside the range will be displayed.

Pressing the Reset button, resets the range to the minimum and maximum values of the currently selected Fault Property data.

To operate the filter:

Type the lower and upper limits for the range into the white data entry boxes.

Set the Inclusive toggle button if appropriate

Then press OK or Apply

Fault Views box

Faulted cell faces can be displayed by a colour-fill controlled by the active cell and/or fault property.
The currently selected Fault property can be displayed at Connections. However if the reservoir is completely offset, TransGen does not display fault properties for unconnected (or inactive) cells.  It is possible to display a cell property on the Upthrow or Downthrown side of the fault.  The cell edges can also be added

The active fault property is selected by the Fault Properties menu.
Fault colours are controlled by the Fault Colourmap editor.
The active cell property is selected by the Cell Properties menu.
Cell colours are controlled by the Cell Colourmap editor.

The fault views box controls whether:

The active Fault Property is displayed at faulted cell-cell Connections in the appropriate fault colours. (The region of juxtaposition)

The active Cell property from the Upthrown side of the fault is displayed in the appropriate cell colours.

The active Cell Property from the Downthrown side of the fault is displayed in the appropriate cell colours.

The fault views box also controls whether:

The Outline of faulted cell faces are drawn at faulted Connections.  These are drawn in black if a fault connection property is displayed or in white if no property is displayed.

The outline of Upthrown cell faces are drawn  These are drawn in black if an upthrown cell property is displayed or in white if no property is displayed.

The outline of Downthrown cell faces are drawn  These are drawn in black if an Downthrown cell property is displayed or in white if no property is displayed.

To use the box, select the Property and/or Outline then press OK or Apply

Always display ViewGen generated faults

By default, this option is toggled "on" to display any faults not imported into TransGen from the Eclipse model, but generated by ViewGen by the offset of cell corners.
Toggle it "off" to remove these ViewGen generated faults from the viewer window, then click on either OK or Apply to update the display in the ViewGen window.

The Close button dismisses the Fault Controls window with no further changes being made.
