About fixed head nodes

The head (or water level) in these nodes is fixed throughout the simulation. You can enter a constant head for the duration of the simulation, or a series of head levels over a 24-hour period. This can be useful for modelling transfers from trunk mains, for which the pressure has been logged. Typical examples are:

A fixed-head point effectively splits the system in two parts, mutually independent - except for the same value of pressure at the node.

You cannot attach any demand to these nodes.
