Output Parameters
155
Figure 5.40 Visualisation (3D) of instantaneous surface elevation using MIKE Ani-
mator Plus, where input is a dfs2 file including the surface elevation.
P flux
The prognostic variable P flux is the depth-integrated flux density in x-direc-
tion.
Q flux
The prognostic variable Q flux is the depth-integrated flux density in y-direc-
tion.
Still water depth
The still water depth is identical to the bathymetry and will not change in time.
For result presentation of 1DH applications it is often useful to include this
parameter in the output.
Auxiliary variable (1DH module only)
This prognostic variable is relevant to save in connection with debugging
model results. The auxiliary variable is defined as
(5.9)
where

is the surface elevation.
Roller thickness (2DH module only)
The roller thickness can be interpreted as a measure of the intensity of wave
breaking. Outside the surf zone the roller thickness is zero.
The definition of the roller thickness is given in Sørensen et al (2004) which is
included in the scientific documentation.
Roller angle (2DH module only)
When wave breaking is included you can save the roller angle. The concept
of surface rollers and definition of the roller angle is given in the scientific doc-
