A Concise Representation of Geometry Suitable for Mesh Generation
نویسندگان
چکیده
We describe a new geometric representation scheme suitable for finite element mesh generation. The representation is by boundaries (i.e., brep) and relations between boundaries are stored as a directed acyclic graph. The geometry itself is based on NURBS curves and surfaces. The new geometry proposal has been been adopted by the CornellMississippi State joint ITR project. We describe why the geometric representation scheme is well-suited for mesh generation and engineering analysis.

A mesh generation procedure to simulate bimaterials
It is difficult to develop an algorithm which is able to generate the appropriate mesh around the interfaces in bimaterials. In this study, a corresponding algorithm is proposed for this class of unified structures made from different materials with arbitrary shapes. The non-uniform mesh is generated adaptively based on advancing front technique available in Abaqus software. Implementing severa...
متن کاملREVERSE LOOP SUBDIVISION FOR GEOMETRY AND TEXTURES
Reverse subdivision aims at constructing a coarser representation of an object given by a fine polygon mesh. In this paper, we first derive a mask for reverse Loop subdivision that can be applied to both regular and extraordinary vertices. The mask is parameterized, and thus can also be used in reversing variants of Loop subdivision, such as those proposed by Warren and Litke. We apply this mas...
متن کاملNumerical optimization of hydrofoil geometry for a Darrieus hydraulic turbine using dynamic mesh and central composite design
In this study, a Darrieus hydraulic turbine for power generation applications is chosen and the response surface methodology (RSM) based on central composite design (CCD) is applied to obtain the optimized design for its hydrofoil geometry to increase the torque coefficient. For this aim, all turbine performance factors, except hydrofoil geometry, were considered to be constant and the turbine ...
متن کاملQuadtree and Octree Grid Generation
Engineering analysis often involves the accurate numerical solution of boundary value problems in discrete form. Hierarchical quadtree (or octree) grid generation offers an efficient method for the spatial discretisation of arbitrary-shaped two- (or three-) dimensional domains. It consists of recursive algebraic splitting of sub-domains into quadrants (or cubes), leading to an ordered hierarchi...
متن کاملUnstructured Tetrahedral Mesh Generation Technology
The whole process of mesh generation is presented in detail. Advancing front technique (AFT) is proposed for 3D tetrahedral mesh generation [1]. AFT starts from initial front. Initial front is a boundary surface conformal triangulation. On each step a new tetrahedron is constructed and the front is updated. At this point local mesh size could be selected automatically in order to create quasi-u...
