This element is a GLS/ASGS fractional step based incompressible fluid element, that is programmed in order to be used in conjunction with explicit time integration scheme for the momentum equation (except for the pressure, which is treated implictely using either B-E or C-N time integration scheme).

This element is written taken into account exclusively linear triangle geometry.

The adequate strategy to be used is the runge_kutta_fracstep_GLS_strategy.h, which can be found in the
