Excess Flow and Qx Routing

Excess Flow - Hydraulics for the Rational Method Excess flow (Qx) occurs when more water arrives at a node than the downstream link (pipe) can carry. Or to put it another way: the pipe taking water away from the node is too small. Excess Flow in your network must not be ignored. You MUST deal [...]

Attribute Management for Digital Engineering

Sharing 12d Model data in a Digital Engineering environment is easy, using 12d Model's IFC Express writer. Controlling the flow of data from 12d Model is done by grouping the required attributes into a 'Tree' structure (using the Attribute Manipulator), then choosing to export the attributes in that 'Tree'. Using the 'Attribute Manipulator' to create [...]

Dynamic Drainage – Major and Minor Attribute Groups

Compare Analysis Results for Major & Minor Events Each time a Dynamic Drainage analysis is completed, the results of the analysis are stored as attributes on the nodes and links. These attributes can be exported to spreadsheet and plotted onto plans or longsections. To keep the results of the Dynamic Analysis separate from the results [...]

Setout Strings

Setout strings are strings from a road design that have an effect on (or are used by) the nodes on the Water string Setout Strings are used by 12d Model for three things: To allow setout information for be given for a location other than the node center. An example is where an inlet structure [...]
