Flow Path (Seepage)

 

Overview

IMG_C_ICON_DOT.gifIdentify the flow path and flow quantity values obtained from the Seepage analysis results.

 

Methodology

Flow Path

<Flow path>

 

 

  • Specify the analyzed analysis case and step, and then input the coordinates of the flow path display position (an arbitrary point on the flow path). Snap option can be used to input the coordinate values.

  • Under [Selection Type] option selection method can be chosen: Node or Face. Multi-path selections (definitions) can be created and stored under Flow Path section.
    Press Show button to display defined flow paths.

  • The flow path can be displayed as a line or pipe. For a line, the line thickness and for a pipe, Scale can be used to adjust the size.

  • The flow path color can be selected between Single color and Contour.

  • The arrow grid option is an indicator that represents the flow direction of the flow path. The scale value and number can be used to adjust the arrow size and number of arrows.

  • If the [Leave Previous Flow Path] option is checked, a flow path is displayed for every clicked position on the screen. If this option is unchecked, a flow path is displayed only on the last clicked position.

  • If the [Sensitive] option is checked, the flow net is displayed on the screen immediately. If this option is unchecked, the [Apply] button needs to be pressed in order to display the flow net.

 

 

 

Flow Quantity

  • Specify the analyzed analysis case and step, and then select the nodes where the flow quantity will be calculated.

  • The nodes can be selected and specified on the screen, or [User Input Mode] can be checked to input the node ID if the node number is known.

  • Press the Calculate button to automatically calculate the flow quantity at the nodes, and the calculated flow quantity value is expressed on the dialog.

  • The flow quantity at each node is made up of the flow rate value sum, and (+) indicates inflow while (-) indicates outflow.

  • The node selection method (Node Mode), line/plane definition method (Cutting Mode) and Arbitrary Type are supported.

  • Nodes/Cutting Mode - returns the flow rate by summing the flow rates calculated at the nodes by direct selection or input of the nodal points where the outflow or inflow occurs.

  • Arbitrary type - calculates the flow of elements through any line or plane

  • There are ‘Cutting Line’ and ‘Cutting Plane‘ option in the ‘Cutting Mode’. The ‘Cutting Line’ option calculates flow quantity from nodes within the 'Search Tolerance' by defining ‘2-Points Line’ directly or selecting ‘Edge’. The ‘Cutting Plane‘ option calculates flow quantity from nodes within the 'Search Tolerance' by defining ‘3-Points Plane’ directly or selecting ‘Plane’. The ‘3-Points Plane’ type calculates flow quantity from the infinite plane consisting of three points or the plane only consisting of them with the 'Limited Plane' option.

  • Once the information for calculating flow quantity is created in the ‘Define Information’ dialogue box, it will be registered in the ‘Define List’. Flow quantity can be calculated by duplicate selecting a number of information registered in the ‘Define List’ and they can be modified or deleted as well. The node information included in the checked ‘Define List’ is displayed in the ‘Node ID’ and duplicated same nodes of a number of information will be treated as one.
