umentation. The roller angle is set to “initial breaking angle” (default 20º)
before breaking and to “final breaking angle” (default 10º) after breaking.

Roller celerity, c
x
(2DH module only)
The roller celerity in the x-direction is calculated as described in the scientific
documentation. Usually you would not save this information.
Roller celerity, c
y
(2DH module only)
The roller celerity in the y-direction is calculated as described in the scientific
documentation. Usually you would not save this information.
Water level (roller) (2DH module only)
The water level including rollers is mainly used in connection with 3D visualis-
ation of the instantaneous surface elevation and surface rollers (see e.g.
Figure 5.41) using MIKE Animator Plus. For generation of 3D images and
animations you have to save the water level and water level (roller) into two
separate dfs2 files. You may use the MIKE Animator Plus setup included in
the examples as an template.

using MIKE Animator Plus, where input is two dfs2 files including the
water level and water level (roller), respectively
