Error estimation of a quadratic finite volume method on right quadrangular prism grids
In this paper, we develop a finite volume element method with affine quadratic bases on right quadrangular prismmeshes for three-dimensional elliptic boundary value problems. The optimal H1-norm error estimate of second order accuracy is proved under certain assumptions about themeshes. Numerical results are presented to illustrate the theoretical analysis. © 2008 Elsevier B.V. All rights reser...
متن کاملA Quadrangular Prism of Self Invisibility
A quadrangular prism of self-invisibility is originally reported in this paper. It is a self-invisible unit, which does not depend on any outer refractive materials or reflective mirrors. Four identical triangular prisms with the lateral faces of mirrors, divided into two groups, are symmetrically placed on two transparent rectangular prisms in a symmetrical way. Two identical rectangular prism...
متن کاملSPE 163649: The Multiscale Finite Volume Method on Unstructured Grids
Finding a pressure solution for large-scale reservoirs that takes into account fine-scale heterogeneities can be very computationally intensive. One way of reducing the workload is to employ multiscale methods that capture local geological variations using a set of reusable basis functions. One of these methods, the multiscale finite-volume (MsFV) method is well studied for 2D Cartesian grids, ...
متن کاملQuadrangular Prism of Self-invisibility (ii)
A kind of novel pillar (used to support a windshield) has been designed to replace the conventional ones used in all sorts of vehicles. The prominent advantage of such a pillar is that it appears invisible so that the blind spots caused by A, B, C and D pillars will be diminished to a large extent or even eliminated completely. Therefore, the driver’s view is enlarged considerably. An intrinsic...
متن کاملFurther Research on the Quadrangular Prism of Self-invisibility (i)
A quadrangular prism of self-invisibility has been further researched for its applications to vehicles. Its structure has been calculated and demonstrated strictly and quantitatively, according to the laws of reflection of light and geometric principles. Furthermore, the invisible effect with respect to the position of an observed point was investigated when the observed point shifted from the ...
