zone face westergaard
command
Syntax
- zone face westergaard <keyword ...> <range>
Primary keywords:
Note
- The following nomenclature / equivalence between FLAC3D and FLAC2D is used:
Zone faces = zone surface faces in 3D or zone edges (lines connecting gridpoints) in 2D
There is no 2D equivalence for 3D zone edges
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.- base f
elevation of the base of the reservoir
- density-water f
density of the water in the reservoir
- direction f
reversal direction of the hydrodynamic wave propagation. This direction must be in the horizontal plane.
- factor f
optional coefficient, the default value is 0.743
- height f
height of the water in the reservoir
