Unified particle system for multiple-fluid flow and porous material

Posted on December 15, 2021 by christopherbatty

Bo Ren, Ben Xu, Chenfeng Li Porous materials are common in daily life. They include granular material (e.g. sand) that behaves like liquid flow when mixed with fluid and foam material (e.g. sponge) that deforms like solid when interacting with … Continue reading →

Semi-analytical Solid Boundary Conditions for Free Surface Flows

Posted on December 6, 2021 by christopherbatty

Yue Chang, Shusen Liu, Xiaowei He, Sheng Li, Guoping Wang The treatment of solid boundary conditions remains one of the most challenging parts in the SPH method. We present a semi-analytical approach to handle complex solid boundaries of arbitrary shape. … Continue reading →

A Lagrangian Particle-based Formulation for Coupled Simulation of Fracture and Diffusion in Thin Membranes

Posted on December 6, 2021 by christopherbatty

Chengguizi Han*, Tao Xue*, Mridul Aanjaneya We propose a Lagrangian particle-based formulation for simulating deformation, fracture, and diffusion in thin membrane-like structures, such as aluminium foil, rubbery films, and seaweed flakes. We integrate our model with diffusion processes and derive … Continue reading →
