Currently the focus of research and development effort for new meshing technology is on developing new algorithms for meshing. As a result of this some successful meshing algorithms have emerged, but true automeshing is still elusive. The generation of a meshed model ready for analysis is more involved than merely creating elements. Solid models created in CAD systems often need to be processed...

In order to study the dynamic meshing characteristics of the elliptic cylinder gear and obtain the meshing error of the gear transmission system, the two-dimensional static contact analysis of the gear tooth surface is carried out by using ANSYS software, and the key parts of the contact area of the tooth surface are determined. Then, the dynamic meshing model of the elliptic cylinder gear is e...

Meshing tools are extremely complex pieces of software. Traditionally, they have been built in a one by one basis, without systematically reusing already developed parts. The area has matured so that we can currently think of building meshing tools in a more industrial manner. We propose a layered product line architecture for meshing tools that can be instantiated with different algorithms, wa...

A single screw compressor is an important element found in many refrigeration systems. A single screw compressor with column envelope meshing pair will have long operating life than existing single screw compressors, although it is still fail to meet industrial applications. To accelerate the industrial application of the new type compressor, a design method of column envelope meshing pair is p...

A novel method is presented for automatically generating quadrilateral meshes on arbitrary two-dimensional domains. Global minimization of a potential function governs mesh formation and characteristics. Comprised of several terms, the potential function distributes the elements throughout the domain and aligns the edges of the elements to form valid connectivities. If there are any remaining u...

We are concerned with Delaunay mesh generation methods and mesh adaptivity issues Planar surface and volume meshing have been automated to a large extent Over the last few years meshing activities have been focused on adap tive schemes where the features of a solution eld must be accurately captured To this end meshing techniques must be revisited in order to be capable of complet ing high qual...

The transform relation between the meshing position and rotation angle of a cylindrical gear pair is firstly derived according to the theory of gear meshing. Then the technique of building the assembly model of a cylindrical gear pair at specified meshing position in ANSYS is researched. On this basis, a new method to perform static contact analysis of cylindrical gear at any meshing location i...

Creating an appropriate mesh is one of demanding tasks of many global illumination algorithms. Discontinuity meshing proved to diminish artifacts caused by other meshing strategies. Since naive discontinuity meshing would produce a great amount of geometric computations, accelerating techniques are usually involved. In this paper, we present results obtained with help of k-discrete orientation ...
