Visual Smoke Simulation with Adaptive Octree Refinement
Three dimensional fluid simulation becomes expensive on high resolution grids which can easily consume a large amount of physical memory. This paper presents an octreebased algorithm for visual simulation of smoke on ordinary workstations. This method adaptively subdivides the whole simulation volume into multiple subregions using an octree. Each leaf node in the octree also holds a uniform sub...
متن کاملFinite element algorithm with adaptive quadtree-octree mesh refinement
Certain difficulties with the use of quadrilateral or hexahedral finite elements are related to mesh refinement and to element compatibility and quality after refinement. In this paper, special refinement elements are presented that make possible connecting two special elements to one edge of an 8-node quadrilateral element (2D). The main idea in refinement elements is to place some midside nod...
متن کاملAdaptive Mesh Refinement for Global Magnetohydrodynamic Simulation
The first part of this paper reviews some physics issues representing major computational challenges for global MHD models of the space environment. These issues include: (i) mathematical formulation and discretization of the governing equations that ensure the proper jump conditions and propagation speeds, (ii) regions of relativistic Alfvén speed, (iii) regions dominated by strong intrinsic p...
متن کاملA Lattice Boltzmann Method with Adaptive Mesh Refinement (AMR) for the simulation of gas-liquid flows
Two-phase flows with dynamic interfaces are ubiquitous in daily life as well as in many industrial applications. Gas bubbles and liquid droplets are typical forms of these twophase flows. In chemical engineering, understanding the dynamics of these bubbles and droplets is crucial to the design and operation of the two-phase flow reactors, ranging from microfluidic devices to large systems such ...
متن کاملNumerical simulation of primary atomization in diesel spray at low injection pressure
Atomization involves complex physical processes and interaction gas-liquid. Primary atomization on Diesel spray is not well understood due to the difficulties to perform experimental measurements in the near nozzle field. Hence computational fluid dynamics (CFD) has been used as a key element to understand and improve Diesel spray. A recently new code for incompressible multiphase flow with ada...
