| Abstract |
We introduce a metric to determine when particle shifting is expected to improve the convergence of weakly compressible Lagrangian SPH. Shifting regularizes particle positions by biasing them toward a more homogeneous distribution. However, shifting also introduces an additional discretization error. To quantify these two opposing effects, we analyze the two- dimensional Taylor-Green case and show that particle shifting is advantageous when there is strong-enough distortion in the particle distribution. We propose a dimensionless metric of particle distortion to predict this break-even point, which we show to behave qualitatively similar across simulation cases. Since the proposed metric can be computed in a running simulation, it can be used to control the onset of shifting. |
