film_height#
EQ = film_height {Galerkin_wt} FILM_HEIGHT {Interpol_fnc} <floatlist>
Description / Usage#
This is the equation card for the film height 2.5D equations for film casting problems. It is used in conjunction with momentum1 and momentum2 cards as well as mesh1 and mesh2 cards to solve film casting problems.

Note: These multipliers are intended to provide a means of activating or deactivating terms of an equation, and hence should be set to zero or one. If a multiplier is zero, the section of code that evaluates the corresponding term will be skipped.
Examples#
The literature suggests treating the film_height equation like pressure and using Taylor-Hood like elements for velocity and film_height combinations.
