Toward Efficient FSI Modeling in Patient-Specific Arteries: SPH Simulation of Blood Flow in Thin Deformable Vessels
Chenxi Zhao, Dong Wu, Weiyi Kong +2
Accurate simulation of blood flow in deformable vessels is critical in cardiovascular research for understanding disease progression and informing clinical decision-making. However…
Heat transfer simulation of window frames with SPHinXsys
Haotian Ji, Dong Wu, Chi Zhang +1
Maintaining a comfortable temperature inside a building requires appropriate thermal insulation of windows, which can be optimised iteratively with numerical simulation. Smoothed p…
A generalized non-hourglass updated Lagrangian formulation for SPH solid dynamics
Shuaihao Zhang, Dong Wu, Sérgio D. N. Lourenço +1
Hourglass modes, characterized by zigzag particle and stress distributions, are a common numerical instability encountered when simulating solid materials with updated Lagrangian s…
A generalized essentially non-hourglass total Lagrangian SPH solid dynamics
Dong Wu, Xiaojing Tang, Shuaihao Zhang +1
In this paper, we tackle a persistent numerical instability within the total Lagrangian smoothed particle hydrodynamics (TLSPH) solid dynamics. Specifically, we address the hourgla…
