A Stabilized Incompressible SPH Method by Relaxing the Density Invariance Condition

Journal of Applied Mathematics, 2012
A stabilized Incompressible Smoothed Particle Hydrodynamics (ISPH) is proposed to simulate free surface flow problems. In the ISPH, pressure is evaluated by solving pressure Poisson equation using a semi-implicit algorithm based on the projection method.
