Abstract We propose a fast and effective technique to improve sub-grid visual details of the grid based fluid simulation. Our method procedurally synthesizes the flow fields coming from the incompressible Navier-Stokes solver and the vorticity fields generated by vortex particle method for sub-grid turbulence. We are able to efficiently animate smo...

We propose a hybrid method for simulating multiphase fluids such as bubbly water. The appearance of subgrid visual details is improved by incorporating a new bubble model based on smoothed particle hydrodynamics (SPH) into an Eulerian grid-based simulation that handles background flows of large bodies of water and air. To overcome the difficulty in...
Article
Developing suitable interpolation methods to simulate dynamic motions of continuous materials such as fluids is an important problem. In this paper, we propose a novel method to enforce the divergence condition to the interpo-lated velocity field by moving least squares, by means of the diffusive derivatives and moving divergence constraints that a...

... In [37,60], two different mathematical models have been solved by an adaptive multilevel Monte Carlo algorithm and mixed finite element methods. Other numerical methods, which have been developed or can be applied to solve these problems in fluid dynamics, can be found in [1,3,15,[11][12][13][29][30][31]52]. Also, we refer the interested reader to [38,39] for seeking the Bayesian inversion method, which may be applied to the mentioned problems that appeared in different situations of fluid dynamics. ...
... Physics-based fluid simulation has been used to realize various visual special effects to simulate water [1,2], fire [3][4][5], smoke [6][7][8], fire-flake [9][10][11], foam [12,13], bubble [14,15], and mist (or spray) [16,17]. When expressing water, the associated secondary effects such as foam, bubble, and splash are caused by oscillating movements, and various approaches have been proposed to efficiently model these characteristics [18,19]. ...
