GfsBcFlather

From Gerris

GfsBcFlather is used to impose "Flather" conditions on the boundaries of a GfsOcean simulation.

The syntax in parameter files is:

[ GfsBc ] [ GfsFunction ] H P [ GfsFunction ]

where H is the name of the depth variable, P the pressure/elevation variable. The first GfsFunction defines the target normal velocity value and the second GfsFunction the target value of the pressure/elevation. Note that the variable this condition applies to (specified with GfsBc) must be the normal component of the velocity field.

Examples

• Lunar tides in Cook Strait, New Zealand

        BcFlather V 0 H P M2(t)

        BcFlather V 0 H P M2(t)
