Mesh Generation Methods Over Plane and Curved Surfaces
نویسندگان
چکیده
In this paper, a set of mesh generation methods over plane and curved surfaces is presented. The surfaces can be plane, just defined by their boundary (as cylinders or cones), quadrics, surfaces of revolution or a combination of these by means of a multiblock definition. The basic method for plane surfaces and those defined by their boundary is based on a advancing front / algebraic combined technique for two dimensions. Quadrics and surfaces of revolution are transformed from the real space into a parametric plane, in which the previous basic method can be applied and, later, the inverse transformation is done to obtain the final mesh.

Generation 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. ...

متن کاملAn Extension of the Advancing Front Method to Composite Geometry
This paper introduces a new approach to automatic mesh generation over composite geometry. This approach is based on an adaptation of advancing front mesh generation techniques over curved surfaces, and its main features are : elements are generated directly over multiple parametric surfaces: advancing front propagation is adapted through the extension to composite geometry of propagation direc...
متن کاملUniversal Meshes: Computing Tetrahedralization Conforming to Curved Surfaces
Three dimensional realistic simulation are often unsteady and include moving domains. One of major challenges associated with such simulations is the robust mesh generation for the moving domain. There has been significant research and development in this specific field[1, 2, 3, 4]. We describe a method for generating conforming tetrahedral mesh to the given C continuous surfaces in R immersed ...
متن کاملEnergy-Minimizing Approach to Meshing Curved Wire-Frame Models
In the initial phase of structural part design, wire-frame models are sometimes used to represent the shapes of curved faces. Finite element analysis (FEA) of the curved faces requires that a well-shaped, well-sized mesh be smoothly generated on them. The algorithm described in this paper generates such a mesh from a wireframe model by the following three steps: (1) projection of the vertices o...
