Triangular Element Re nement in Automatic Adaptive Mesh
نویسندگان
چکیده
| A new reenement strategy is proposed for use in an adaptive procedure. The method developed places new nodes in regions of high solution error such that the beneet of the Delaunay re-triangulation algorithm is fully realised. Results show that the improved mesh geometry obtained with this method compared with the conventional centroid approach produces a more eecient mesh, where less nodes are needed to obtain the same solution accuracy. New algorithms with the purpose of removing thin elements and obtaining a gradual transition in node density in the mesh after each reenement step are also described.

The numerical solution of incompressible Navier-Stokes equations for ows involving complex geometries is greatly a ected by mesh resolution. In these ows, some regions may need ner mesh than others. Adaptive Mesh Re nement (AMR) techniques enable the mesh to be locally re ned, based on error distribution in the previous analysis.

A grid re nement scheme has been developed for tetrahedral and triangular grid-based calculations in message-passing environments. The element adaption scheme is based on edge bisection of elements marked for re nement by an appropriate error indicator. Hash table/linked list data structures are used to store nodal and element information. The grid along inter-processor boundaries is re ned con...
متن کاملGeneration of quadrilateral mesh over analytical curved surfaces
An automatic adaptive quadrilateral mesh conversion scheme for the generation of adaptive refinement meshes over analytical curved surfaces is proposed. The starting point of the quadrilateral mesh generator is a background triangular mesh of the curved surface. By a carefully controlled process to merge two triangles at a time the triangular mesh can be completely converted to quadrilaterals. ...
