Particle-wall interaction is important in various applications such as cell sorting, particle separation, the entire class of hydrodynamic filtration and its derivatives, etc. Yet, accurate implementation interactions between wall finite-size particles not trivial when working with currently available tracking algorithms/packages they typically work point-wise particles. Herein, we report a algorithm that takes into account finite size nearby solid objects. A modeled set circumferential points. While fluid-particle are captured during track center, objects explicitly by examining points applying reflection scheme needed to ensure impenetrability We also modified variant auxiliary structured grid method locate hosting cells, which conjunction boundary condition enables capture As proof-of-concept, numerically experimentally study particles' motion within deterministic lateral displacement microfluidic device. The results successfully demonstrate zigzag bump modes observed our experiments. device pinched flow validate against experimental data from literature. By demonstrating an almost 8 × speedup on system eight performance threads, investigations suggest can benefit parallel processing multi-thread systems. believe proposed framework pave way for designing related chips precisely conveniently.
