dc.description.abstractHigh viscosity fluid simulation remains a significant area of interest within the graphics field. However, there are few discussions about simulating viscous fluids in computer graphics with the Lattice Boltzmann Method (LBM). In this study, we demonstrate the feasibility of using LBM for viscous fluid simulation and show a caveat regarding external forces. Previous methods (such as FLIP, MPM, SPH) on viscous fluids are mainly based on Navier-Stokes (NS) Equation, where the external forces are independent from viscosity in governing equation. Therefore, the decision to neglect the external force solely depends on its magnitude. However, in the context of the Lattice Boltzmann Equation (LBE), external forces are intertwined with viscosity within the collision term, making the choice to ignore the external force term dependent on both the viscosity and the force's magnitude. It has not been mentioned in previous study and we will show its importance by comparison experiments.en_US
