Flow motion on curve surfaces of arbitrary topology is an interesting visual effect but a complex dynamics to simulate. In this paper, we introduce a novel and effective way to modal such dynamics. We propose a technique that adapts a unstructured lattice Boltzmann model (Unstructured LBM). The whole algorithm consists of five aspects, including surface modeling with unstructured triangular meshes,...
In this paper, an operational matrix of integration based on the Haar wavelet is established, and the procedure for applying the matrix to solve the wave equation which satisfies the boundary conditions and initial conditions is formulated. The fundamental idea of Haar wavelet method is to convert the wave equation into a group of algebra equations which involves a finite number of variables. The...
The papers discuss the temperature field calculation for solidification process of casting which based on cut cell. It deals with latent heat of solidification process with temperature recovery method. The temperature field of the dumbbell casting was calculated based on cut cell and zigzag mesh, the results show the calculation precision with cut cell is higher than zigzag mesh at the same grid size...
