Simulation of the solution of a viscous porous medium equation by a particle method

摘要

To solve a particular partial differential equation, namely a viscous porous medium equation, we discuss a particle method, which is based on the concept of moderately interacting many-particle systems. Our approach may be classified as a combination of a smoothed particle hydrodynamics method and a particle-mesh method. Quantitatively, it is assessed in terms of estimates on the approximation error. [References: 18]
