semi-structured mesh formationturbomachinery bladesThis paper describes the development and application of a novel mesh generator for the flow analysis of turbomachinery blades. The proposed method uses a combination of structured and unstructured meshes, the former in the radial direction and the latter...

To date, IB methods employ structured grids, which allow only limited control on the distribution of the grid points in the computational domain; in fact, clustering of grid points is needed close to solid boundaries in order to describe its geometry accurately and, since mesh lines run through...
Surface blending is a useful operation in geometric design for rounding sharp edges or corners. Meanwhile, NURBS has already become the de facto industrial standard in existing CAD/CAM systems. Therefore, it is required to study how to blend two B-spline surfaces. However, two arbitrary B-splin...
In our technique, semigeodesic coordinates are constructed at each vertex of the mesh which becomes the local origin. A geodesic from the origin is first... F Mokhtarian,N Khalili,P Yuen - 《Computer Vision & Image Understanding》 被引量: 62发表: 2001年 加载更多来源...
Representing the MeSH in OWL: Towards a semi-automatic migration Due to the numerous health documents available on the Web, information retrieval remains problematic with existing tools. This paper is positioned within the context of the CISMeF project (acronym of Catalogue and Index of French-...
The proposed semi-structured mesh formulation was found to have a number of advantages over its structured counterparts. There is a significant improvement in the smoothness of the grid spacing and also in capturing particular aspects of the blade passage geometry. It was also found that the ...
The resulting semi-structured mesh possesses significantly fewer degrees of freedom than the equivalent unstructured mesh, validating the effectiveness of the approach.doi:10.1007/978-3-642-24734-7_11Jonathan E MakemJ.

Semi-structured meshBoundary element methodCross-fieldIn this paper, a boundary element-based approach is proposed for partitioning a planar domain automatically into a set of 4-sided regions, which is suitable for semi-structured quad mesh generation. The basic idea is to generate a smooth cross...
Details of a flow algorithm which operates on a hybrid mesh are presented. A description is given of the suitability and generation of hybrid grids for a number of examples, and results from flow simulations shown. Finally, issues still to be addressed in the practical use of these meshes ...
