Grid-characteristic method on unstructured tetrahedral meshes

Computational Mathematics and Mathematical Physics, 2014
Summary: The goal of this paper is to develop a grid-characteristic method intended for high-performance computer systems and implemented on unstructured tetrahedral hierarchical meshes with the use of a multiple time step and high-order interpolation, including interpolation with a limiter, piecewise parabolic interpolation, and monotone interpolation.

Convergence Analysis for the Method of Characteristics in Unstructured Meshes

Nuclear Science and Engineering, 2016
A new conservative linear surface approximation (CLS) has been recently introduced to speed up the method of characteristic in unstructured meshes (MOC). In this work we present an analysis of convergence of the CLS that shows that, under optimal conditions, the method converges quadratically with the size of the regions, while the classical step ...

Transmission characteristics of copper mesh at 118.8 μm

Infrared Physics & Technology, 1995
Abstract An experimental investigation of the optical transmission characteristics of an electroformed copper wire mesh at an angle of 45° to incident radiation at 118.8 μm is reported. It is shown that the transmission coefficient is highly sensitive to the input beam polarization and the results obtained are in good agreement with those reported ...

Acceleration techniques for the characteristic method in unstructured meshes

Annals of Nuclear Energy, 2002
Abstract Acceleration techniques are essential for the efficient iterative solution of the transport equation in reactor applications. We present two new acceleration techniques for the method of characteristics in unstructured meshes. The DPN scheme generalizes a previous asymptotic acceleration by incorporating a general DPN angular approximation ...

Tooth profile design and meshing characteristics analysis of internal meshing gears based on variable center meshing line

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science
A design method of internal meshing gear based on variable center meshing line (VCML) is presented in this paper. The meshing line is an arc line connecting the intersection of the indexing circle connecting the inner and outer gears and the intersection of the tooth top circle, and the center of the line of engagement freely slides on the vertical ...
