Description🔗
The inclinedFilmNusseltInletVelocity
is boundary condition that provides
a film velocity boundary condition for inclined films that imposes a
sinusoidal perturbation on top of a mean flow rate, where the velocity is
calculated using the Nusselt solution.
Usage🔗
The condition requires entries in both the boundary and field files.
