ABSTRACT
Glazed frost is a crystal clear ice and formed from supercooled raindrops that freeze when they hit object surfaces such as the ground and branches of trees. Simulation methods for formation of ice crystal, such as frost, on the surface of objects have been proposed by Kim et al. [Kim et al. 2004]. However, a supercooling state has to be considered for simulating freezing rain, and fluid simulation is required for reproducing the effect of raindrops running down on the ice surfaces. To our best knowledge, there has been no research presenting glazed frost by using a fluid simulation. We use the fluid simulation based on FLIP method [Zhu and Bridson 2005]. Hence, raindrops and obstacles are represented by particles which are used to calculate the advection term, and the update of velocity field are calculated by using grids except for advection term. We propose a method to create an animation of glazed frost formation by taking into account the heat transfer between particles and the outside grids.

Visual simulation of freezing ice with air bubbles
SA '12: SIGGRAPH Asia 2012 Technical BriefsIce often contains small air bubbles that are dissolved air exhausted from water-ice interface. Depicting these air bubbles with various sizes enhances the realism of ice. This paper proposes a fast simulation method of freezing ice taking into account ...

A Revised DLA Model for Simulation of Frost Formation and Growth
IWCFTA '11: Proceedings of the 2011 Fourth International Workshop on Chaos-Fractals Theories and ApplicationsA revised diffusion limited aggregation (DLA) model based on the heat balance and mass balance is proposed. The computational simulation is carried out and compared with experiment data. The results indicate that revised DLA model can simulate the ...
