Option

Description

Analyze all or just selected nodes

Select All to analyse all the branches and links; and Marked to only analyse those selected using Graphical Mark.

Options

Renumber branches and links

If this is the first time you are analysing the entire network, you must select this option.

If you have already numbered branches and links, a confirmation message displays.

Keep existing subnetworks

Locks the subnet numbering to the previously calculated numbering, and can only be used if you have renumbered branches and links.

Error check the existing link numbering

Checks for duplicate subnet, branch and link numbering.

Re-calculate link lengths from coordinates

Calculates the length of each link from the coordinates of the upstream and downstream node coordinates.

Keep previously calculated levels and sizes

Locks the levels and link sizes to the previously calculated ones. This is useful when you have designed the network for one flow and wish to check for larger flows on the same network.

Select main branch manhole condition

Allows you to set dual manhole conditions for the main line and trunk line. The standard conditions apply to the trunk line and you can specify the conditions for the main line using the dropdown list:

• Invert

• Soffit

• Drop

• 1/2 Pipe
