GfsBcNavier

From Gerris

GfsBcNavier is used to impose a Navier slip condition (for velocity or Robin boundary condition for a tracer) of the form

v_boundary = v₀ + λ ∂_n v_boundary

where ∂_n is the derivative normal to the boundary and v₀ and λ are parameters.

The syntax in parameter files is

[ GfsBc ] V0 LAMBDA

where V0 and LAMBDA are the parameters. Both V0 and LAMBDA are GfsFunctions.
