An 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...
متن کاملAutomatic Mesh Motion for the Unstructured Finite Volume Method
Moving-mesh unstructured Finite Volume Method (FVM) is a good candidate for tackling flow simulations where the shape of the domain changes during the simulation or represents a part of the solution. For efficient and user-friendly approach to the problem, it is necessary to automatically determine the point positions in the mesh, based on the prescribed boundary motion. In this paper, we prese...
متن کاملAdaptation of Structured Grid for Supersonic and Transonic Flows
Two distinct redistribution grids - adaptation techniques, spring analogy and elliptic grid generator are applied to two-dimensional steady, inviscid, shocked flows, and the ability of each technique is examined and compared. Euler equations are solved base on Roe's Reimann solver approach to simulate supersonic flow around a sphere, transonic flow about an airfoil and supersonic flow in a symm...
متن کاملAn unstructured-grid, finite-volume, nonhydrostatic, parallel coastal ocean simulator
A finite-volume formulation is presented that solves the three-dimensional, nonhydrostatic Navier–Stokes equations with the Boussinesq approximation on an unstructured, staggered, z-level grid, with the goal of simulating nonhydrostatic processes in the coastal ocean with grid resolutions of tens of meters. In particular, the code has been developed to simulate the nonlinear, nonhydrostatic int...
متن کاملOn a solution reconstruction and limiting procedure for unstructured finite volumes
The present paper deals with the continuous work of extending the application of a multidimensional-type solution reconstruction and limiting procedure into the finite volume (FV) computation of 2D compressible flows. Based on a MUSCL-type technique, this reconstruction procedure identifies and cures poor connected grids without suffering from loss of accuracy by taking into account geometrical...
