zone face westergaard command

Syntax

zone face westergaard <keyword ...> <range>

Primary keywords:

direction    height    base    density-water    factor

Applies the Westergaard approximation for the dynamic response of water to the surface faces in the range. This operates by changing the inertial mass of the gridpoints connected to the surface faces in the range. This command is only available if model configure dynamic has been specified.

As with most zone face commands, this command will only operate on surface faces in the range.

direction f

reversal direction of the hydrodynamic wave propagation. This direction must be in horizontal plane.

height f

height of the water in the reservoir

base f

elevation of the base of the reservoir

density-water f

density of the water in the reservoir

factor f

optional coefficient, the default value is 0.743
