capture zone

capture zone

The capture zone module utilizes 3d streamlines technology to determine the volumetric regions of your model for which groundwater flow will be captured by one or more extraction wells.

Ports

DirectionNameTypeDescription
InputInput FieldFieldA field containing vector data representing seepage velocity.
InputWell NodesFieldThe field containing nodes to use as starting locations.
InputZ ScaleNumberThe factor for vertical scaling.
OutputOutput FieldFieldA field containing the input field with three additional data components.

Properties

PropertyTypeDescription
ExecuteButtonThe Execute button will cause the module to run with the current settings.
Z ScaleDoubleThe Z Scale is the vertical exaggeration of the Input Field.
Seepage Velocity ComponentChoiceDisplays all data components (vector and scalar) passed to the module.
Well Capture DistanceDoubleThe maximum distance that a streamline must pass near an extraction well before that streamline’s integration is terminated and its original starting location is deemed to have been captured by a well. Generally a value corresponding to one nominal cell width in the region of your wells is appropriate.
Minimum Flow VelocityDoubleThe minimum velocity that will be considered in the integration. If the magnitude of the velocity field in a region is less than this value, streamlines will end in that region. Setting this to a lower value will more accurately define the full extent of the capture zone region, but may increase run time.
Export Well DataBooleanWhen enabled, uses the selected Nodal Data component label as the name of the output data.
Segments Per CellIntegerThe number of integration steps to be used in each cell to calculate the streamline.
OrderIntegerThe order of the integration. Higher order integration is more accurate but executes much slower.
Max Segments TotalIntegerThe maximum allowable number of streamline segments that will be completed for each streamline. If the number of segments along a streamline exceeds this value, the streamline is terminated at the end of the last segment.
Extinction AngleDoubleThe maximum allowable angle between successive line segments before integration (streamline generation) should be terminated.
