Shape Data Fields

Shape data can be edited on either the Shape Grid Window of the Links Grid or the Shape Property Sheet.

Remember that when defining an asymmetrical shape, the shape is always defined and viewed in the preview window as if looking in the upstream direction.

This table describes all the shape specific data which can be used to define a conduit / bridge opening shape.

Common Data Fields

Fields that are common to the majority of objects can be found in the Common Fields topic.

Shape Type

Choose either Asymmetric or Symmetric from the drop-down menu. The other possible type is Built-in. Built-in shapes cannot be added or edited. Changing the type will change the data describing the shape stored in the database. Changing from Asymmetric to Symmetric may result in loss of data.

Height

Height of shape at corresponding width value.

When the Normalised option is checked, this must be between 0 and 1. Heights must be given in ascending order with the last value being 1.

If the first height is non-zero then InfoWorks ICM assumes that the width is zero at height zero and that the base of the shape is at the central point.

If the last height is not 1 then InfoWorks ICMassumes that the width is zero at height 1 and that the top of the shape is at the central point.

height

Width (Symmetric shape type)

Left hand side (Asymmetric shape type)

Width of shape at corresponding height value (symmetric shape).

Position of the left-hand side of the cross-section (asymmetric shape)

When the Normalised option is checked, the range is 0.0 (far left) to 1.0 (far right).

To define an open pipe, enter different left and right values at height = 1. For a closed pipe, define equal left and right values at height 1, or do not put in an entry for height.

left

Double

Right hand side (Asymmetric shape type)

Position of the right-hand side of the cross-section.

When the Normalised option is checked, the range is 0.0 (far left) to 1.0 (far right).

To define an open pipe, enter different left and right values at height = 1. For a closed pipe, define equal left and right values at height 1, or do not put in an entry for height

Normalised

When this option is checked, the Geometry of the shape is defined by a set of height and width factors between 0 and 1. Actual width and height of the conduit / bridge opening with which the shape is associated is determined by multiplying the normalised profile by the values in the cross section Height and Width fields of the conduit / bridge opening.

All built-in shapes are normalised.

When this option is unchecked, the Geometry of the shape can be defined by actual height and width values. Note that the shape profile is dimensionless. The profile will be normalised by InfoWorks prior to simulation. As above, width and height of the conduit / bridge opening is determined by multiplying the normalised profile by conduit / bridge opening Height and Width.

See User-defined Shape for further details.
