Molecular dynamics-based unstructured grid generation method for aerodynamic applications
A new approach to triangular mesh generation based on the molecular dynamics method is proposed. Mesh nodes are considered as interacting particles. After the node placement by molecular dynamics simulation, well-shaped triangles or tetrahedra can be created after connecting the nodes by Delaunay triangulation or tetrahedrization. Some examples are considered in order to illustrate themethod’s ...
full textAn automatic unstructured grid generation method for viscous flow simulations
High aspect-ratio grids are required for accurate solution of boundary layer and wake flow. An approach for the efficient generation f isotropic and stretched viscous unstructured grids is introduced in this paper. The proposed grid generation algorithm starts with very coarse initial grid. In far field regions, isotropic cells of excellent quality are produced using a combination of point inse...
full textAn Open Framework for Unstructured Grid Generation
Traditionally, individual algorithm developers directly incorporate the requirements of their scheme into its resulting software implementation. While this is sufficient for basic execution, it severely limits the expandability and growth potential of the algorithm. An example of such a shortcoming is a fixed method of geometry access in a surface triangulation algorithm. By adopting a single d...
full textAdaptive Unstructured Grid Generation Scheme for Solution of the Heat Equation
An adaptive unstructured grid generation scheme is introduced to use finite volume (FV) and finite element (FE) formulation to solve the heat equation with singular boundary conditions. Regular grids could not acheive accurate solution to this problem. The grid generation scheme uses an optimal time complexity frontal method for the automatic generation and delaunay triangulation of the grid po...
full textA Paradigm for Parallel Unstructured Grid Generation
In this paper, a sequential 2D unstructured grid generator based on iterative point insertion and local reconnection is coupled with a Delauney tessellation domain decomposition scheme to create a scalable parallel unstructured grid generator. The Message Passing Interface (MPI) is used for distributed communication in the parallel grid generator. This work attempts to provide a generic framewo...
