A Method for Particle Simulation
Journal of Applied Mechanics, 2003This paper extends a recent approach to the direct numerical simulation of particle flows to the case in which the particles are not fixed. The basic idea is to use a local analytic representation valid near the particle to “transfer” the no-slip condition from the particle surface to the adjacent grid nodes.

In this paper, the radial basis function (RBF) is used to construct the approximating function of the reproducing kernel particle method (RKPM), which can eliminate the negative effect of different kernel functions on the calculating accuracy. The radial

A Particle Method for Population Waves
SIAM Journal on Applied Mathematics, 1994Phase models are useful for studying synchronization of bacterial cell culture growth and other biological events associated with cell cycles. This paper considers a model that allows the growth rate of cells to change at different phases of cell cycle.

The dimension splitting reproducing kernel particle method for three‐dimensional potential problems
International Journal for Numerical Methods in Engineering, 2019In this paper, the dimension splitting reproducing kernel particle method (DSRKPM) for three‐dimensional (3D) potential problems is presented. In the DSRKPM, a 3D potential problem can be transformed into a series of two‐dimensional (2D) ones in the ...

The power particle-in-cell method
ACM Transactions on Graphics, 2022This paper introduces a new weighting scheme for particle-grid transfers that generates hybrid Lagrangian/Eulerian fluid simulations with uniform particle distributions and precise volume control. At its core, our approach reformulates the construction of Power Particles [de Goes et al. 2015] by computing volume-constrained density kernels.

A Method for Lamping Atoms into Particles in Particle Dynamic Method
Advanced Materials Research, 2011Generalized particle dynamics method (GP) is a kind of new multi-scale analysis approach which relates various scales naturally through cohering small scale lattice to large-scale lattice. In this paper, a method named nearby condensation method is proposed to lump small scale lattice to large-scale lattice keeping topology structure and mass ...
