GfsBcDirichlet
From Gerris
GfsBcDirichlet is used to impose a Dirichlet boundary condition i.e. the value of the variable on the boundary.
The syntax in parameter files is
GfsBcDirichlet V [ GfsFunction ]
where V is the name of the variable and the GfsFunction is the value of the variable on the boundary.
