Computational efficiency is an important theme in fluid simulation since its heavy computational load is burden to designers. The authors' objective is to proposed a grid based method satisfying divergence free property without the projection method. The paper transforms the momentum conservation part of the Navier-Stokes equations to vector potential based equations. Their method do not need any global operations for mass conservation. The transformed equation is solved numerically in similar manner to fractional step method.
