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...

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 ...

A novel approach for designing an error measure to guide an adaptive meshing algorithm using a POD adjoint or goal-based method, is presented here. In this work the multi-field error measure was applied to each field type at each time level between two points in time where mesh adaptivity is applied. The aim is to obtain a new mesh that can resolve all the fields at all time levels, to an optim...

The applicability of the meshing framework ViennaMesh for finite element simulations is investigated. Meshing tools are highly diverse, meaning that each software package offers specific properties, such as the conforming Delaunay property. The feasibility of these properties tends to be domain specific, thus restricting the general application of ameshing tool. For research purposes, it is des...

A computational mesh defines the discretization of the problem of interest. The mesh provides the geometric and topological basis on which the equations that describe the problem are solved. Mesh generation is an enabling technology for modern computational analysis, as the feasibility of performing a simulation of a complex assembly, such as a nuclear reactor core, is strongly influenced by th...

Considerable progress has been made on automatic hexahedral mesh generation in recent years. Several automatic meshing algorithms have proven to be very reliable on certain classes of geometry. While it is always worth pursuing general algorithms viable on more general geometry, a combination of the well-established algorithms is ready to take on classes of complicated geometry. By partitioning...
