In this paper we propose a particle-based approach to ice melting simulation using heat received from the air assuming to be around an ice object using Newton’s law of cooling. We use the SPH method for handling flowing motion of water coming off from the melting ice surface. However, for melted water that is sparsely generated and flowing on the ice surface, thin features are difficult to simulate only with the SPH-based approach. To avoid unnatural appearance of a few water particles flowing on ice surface, we extract an isosurface from the density distribution of the desired characteristic calculated from melted ice volume transferring to water volume, based on the ratio between current heat of the ice and latent heat of the ice fusion. We also explain a simplicity of our simulation method that reduces computational cost during the heat transfer process.

This paper describes an algorithm for fracture surface extraction from particle-based simulations of brittle fracture. We rely on a tetrahedral mesh of the rest con guration particles and use a simple, table-lookup approach to produce triangulated fracture geometry for each rest con guration tetrahedron based on its con guration of broken edges. Subsequently, these triangle vertices are transformed with a per particle transformation to obtain a fracture surface in world space that has minimal deformation and also preserves temporal coherence. The results show that our approach is e ective at producing realistic fractures, and capable of extracting fracture surfaces from the complex simulation.
