Numerical Computation of Stiff Systems for Nonequilibrium Ionization Problemsribe such physical phenomena, the fluid dynamics systems, multi-group energy equations of photons, electrons, ions and equations for electron occupation probabilities are considered. There are nonlinear coupled ordinary and partial differential equations, which have much different time scales. It is a large scale scientific computing problem.作者: 廣告 時間: 2025-3-22 03:59
Numerical Pathfollowing Beyond Critical Points in ODE Modelsd systems are discussed in detail on the basis of stability considerations for ordinary differential equations. For difference or collocation methods, two efficient augmented systems are given. For multiple shooting techniques, an efficient and theoretically satisfactory treatment could only be found for “not too stiff” ODEs.作者: ADOPT 時間: 2025-3-22 05:05 作者: Protein 時間: 2025-3-22 12:16 作者: Cursory 時間: 2025-3-22 14:18

Extrapolation Integrators for Quasilinear Implicit ODEs Extensions to problems with index = 1, where B is singular, are also included. In large scale scientific computing, problems of the type (0.1) may arise e.g. in chemical reaction kinetics, when thermodynamic equations are added, or in method of lines treatment for time-dependent PDEs with moving spatial grids (compare Miller [8,9], Hyman [6]).作者: 是他笨 時間: 2025-3-24 10:58

Numerical Backprojection in the Inverse 3D Radon Transformmula. Using special functions we demonstrate that, if suitable filters in the first reconstruction step — differenciation of order two — are used, essential errors are produced only outside the region of interest. The directions needed in measuring the data fulfil also another requirement, they guarantee optimal resolution in the reconstruction.作者: 歌唱隊 時間: 2025-3-24 22:13 作者: 絆住 時間: 2025-3-25 00:11
Vortex Dynamics Studied by Large-Scale Solutions to the Euler Equations like the singular points. Several flow problems designed to test the vortex-sheet hypothesis are solved upon a mesh with over 600,000 grid cells. These solutions, even when the body is smooth, present numerical observations of such vortex sheets and singular points which support the hypothesis. One作者: THROB 時間: 2025-3-25 04:11
