[Data structs] FDM-any-accuracy DL : 0: 电磁波、声波或地震波等数值模拟中常常会用到有限差分法，但是很多文章都只是泛泛而谈时间2阶，空间4阶等等如何用公式，本文给出了任意阶精度的泰勒展开与迭代公式。-Numerical simulation of electromagnetic, acoustic or seismic waves will often use the finite difference method, but many articles are just generalities time two bands, space, etc. How to order 4 formula, this paper presents the accuracy of any order Taylor expansion and iterative formula.

[VC/MFC] Celusion DL : 0: Cell centered (LAPc) and cell edge (LAPe) algorithms were developed to solve the static neutron diffusion equation in 2D Cartesian geometry using Lagrange interpolation with the progressive polynomial approximation. Two benchmark problems were used to test the algorithms the two-group TWIGL problem and a one-group IAEA benchmark problem. The LAP algorithms showed to be more accurate than a finite difference method (FDM) and for about the same level of accuracy, the LAP numerical methods have an efficiency advantage because they have to solve for less number of unknowns. The LAP algorithms showed more sensitivity to the mesh size than what QUANDRY results showed. Even though the FDMs algorithm, for the calculation of keff, showed systematically to be less accurate than QUANDRY, LAPc, and that LAPe, it was the only one that did not produce negative flux in any location for all the mesh structures analyzed in the IAEA problem.

[Documents] 书籍computational_fluid_dynamics DL : 0: Computational fluid dynamics has been a hot topic of research these last forty years, and several books have been published on this topics. This book concentrates on the numerical of Computational Fluid Mechanics, followed by some focus of new development of classical methods, and to the recent methods appearing in this field. The present volume presents in nine chapters a selection of some numerical methods used in computational fluid mechanics including: mathematical models in computational fluid mechanics, numerical methods in computational fluid mechanics, finite volume, finite difference, finite element, spectral methods, smoothed particle hydrodynamics methods, mixed-element-volume methods, free surface flow. The topics covered in this book are wide ranging and demonstrate the extensive use in computational fluid mechanics.
