A fractional step projection method is introduced here to achieve incompressibility in the SPH method. Fractional step method is a popular approach used to solve incompressible fluid dynamics problems in traditional grid based methods and involves a two-step process to achieve incompressibility. Essentially, the velocity update over a time step is split into a component that does not take into account the divergence free condition, plus a pressure correction term which restores the incompressibility of the velocity. This paper mainly focuses on the variational formulation of fractional step method for SPH fluid applications by presenting a detailed description of the formulation of governing equations.
