The development and use of divergence filters on quadrilateral grids in connection with a finite-difference-based ink-jet simulation model improves the stability of the code in the model, and allows the use of larger time step size and hence reduces the CPU time. The filters are employed after the finite element projection in each time step and function as additional finite difference projections that are enforced at edge mid-points and at cell centers. The improved model and accompanying algorithm enable more precise control of ink droplet size and shape.
