GfsVariableTracerVOFHeight

From Gerris

GfsVariableTracerVOFHeight is a new implementation of GfsVariableTracerVOF which defines and maintains new variables corresponding to height functions.

The syntax in parameter files is:

[ GfsVariableTracerVOF ]

Whenever a new GfsVariableTracerVOFHeight is created called T for example, four additional variables are automatically created:

T_Hbx

the height function along the (positive) x-direction.

T_Hby

the height function along the (positive) y-direction.

T_Htx

the height function along the (negative) x-direction.

T_Hty

the height function along the (negative) y-direction.

Note that the interface positions corresponding to these height functions can be displayed using the Scalar->Height object of GfsView.
