A discrete divergence-free basis for finite element methods


The divergence-free finite element method (DFFEM) is a method to find an approximate solution of the Navier–Stokes equations in a divergence-free space. That is, the continuity equation is satisfied a priori. DFFEM eliminates the pressure from the calculations and significantly reduces the dimension of the system to be solved at each time step. For the… (More)
