Flux Planes

Description

The flux planes dialog box is used to calculate the flux within fractures passing through one or more specified planes.
The flux planes dialog box is displayed by selecting a realisation item in the session tree and choosing Calculate flux through planes from the right-click menu. Only one flux planes dialog box can be open at once, so this menu item is disabled if the dialog box is already open. If the dialog box is required for a different realisation then the open dialog box must be closed first.
The Calculate flux through planes menu item is not available for items that are not realisations or for realisations that do not have fracture sets.

Buttons

OK

Applies the settings, closes the dialog box, calculates the fluxes and displays the results.
If there have been no changes to the settings then the dialog box just closes and displays the results.

Cancel

Discards any changes since the last Apply, if any, and closes the dialog box.

Apply

Applies the settings, calculates the fluxes, displays the results and leaves the dialog box open.
If there have been no changes then only the results are displayed.

Planes

A table is used to define the planes. Each row in the table represents the definition of a single plane.

The following buttons are available for adding and removing planes:

Add

The Add button adds a new plane to the table.
By default, new planes are defined to be vertical through the centre of the current realisation and equal in size to the largest dimension of the bounding box of the realisation.

Remove

The Remove button removes the selected planes from the table.
Shift or ctrl clicking can be used to select more than one plane.

Clear

The Clear button removes all planes from the table.

The following properties can be set for each plane:

Centre X

The X coordinate of the centre of the plane in metres.

Centre Y

The Y coordinate of the centre of the plane in metres.

Centre Z

The Z coordinate of the centre of the plane in metres.

Strike length

The length of the plane along the plane strike in metres.

Dip length

The length of the plane along the plane dip in metres.

Dip

The dip angle of the plane in degrees.
This is the angle of the plane below the horizontal.

Strike

The strike angle of the plane in degrees.
This is the angle of rotation of the plane around the Z axis. Zero degrees is along the positive Y axis.

Orientation

The orientation angle of the plane in degrees.
This is the angle of rotation of the plane around its own principal axis.

Results

The results of the flux calculations are displayed after the OK or Apply buttons are clicked.
The image below shows the results for two vertical planes 40m apart.

The results dialog box gives a summary of how and when the calculations were carried out followed by a table giving the results for each plane.

Plane

The plane number, starting at one.

Gross flux

The total flux crossing the plane in any direction.

Net flux

The absolute value of the total net flux crossing the plane in a particular direction.

Mean gross velocity

The mean velocity across the plane in any direction.

Mean net velocity

The absolute value of the mean net velocity across the plane in a particular direction.

Clicking the Close button closes the results dialog box.
Clicking the Save button saves the results to a file in HTML format or in comma separated value (CSV) format, suitable for loading into a spreadsheet.
