Flow Feature Aligned Mesh Generation and Adaptation [PDF]
, 2013 Methods which allow for construction of flow feature aligned meshes in two- and three-dimensions have been developed in this thesis to investigate their potential for improvements in the numerical solution relative to globally refining the mesh.

Cover interpolation functions and h-enrichment in finite element method [PDF]
Numerical Methods in Civil Engineering, 2017 This paper presents a method to improve the generation of meshes and the accuracy of numerical solutions of elasticity problems, in which two techniques of h-refinement and enrichment are used by interpolation cover functions.

Adaptive Triangular-Quadrilateral Mesh Generation [PDF]
, 1996 In this paper, we begin by recalling an adaptive mesh generation method governed by isotropic and anisotropic discrete metric maps, by means of the generation of a unit mesh with respect to a riemannian structure.

Effects of Mesh Generation on Modelling Aluminium Anode Baking Furnaces
Fluids, 2021 Anode baking is critical in carbon anode production for aluminium extraction. Operational and geometrical parameters have a direct impact on the performance of anode baking furnaces (ABF), and hence on the resulting anode quality.

Mesh-based video coding for low bit-rate communications [PDF]
, 2006 In this paper, a new method for low bit-rate content-adaptive mesh-based video coding is proposed. Intra-frame coding of this method employs feature map extraction for node distribution at specific threshold levels to achieve higher density placement of ...

Numerical Study of Photoacoustic Pressure for Cancer Therapy
Applied Sciences, 2016 A commonly used therapy for cancer is based on the necrosis of cells induced by heating through the illumination of nanoparticles embedded in cells. Recently, the photoacoustic pressure shock induced by the illumination pulse was proved and this points ...
