Adaptively Refined Cartesian Grid Generation and Euler Flow Solutions for Arbitrary Geometrieserated based on an octree-data structure. Solid bodies merely blank out areas of the background Cartesian grid. The part of the surface-intersecting cells is cut off, which lies inside the body. As a result arbitrarily shaped cut-cells arise around the geometry. The remaining cells inside the flow f作者: 取之不竭 時(shí)間: 2025-3-22 01:53 作者: 危險(xiǎn) 時(shí)間: 2025-3-22 06:05
The appropriate numbering for the multigrid solution of convection dominated problemshat the matrices arising from FE- or FD-discretizations of saddle-point problems are no longer positive definite. One remedy is to use the squared system. This leads to convergence in the symmetric case, but does not work if there is dominant convection. In this paper we will describe efficient smoo作者: 領(lǐng)先 時(shí)間: 2025-3-22 12:21

Turbulent convection driven by an imposed temperature gradient in the presence of a constant vertica simplified by utilization of the homogeneity assumption. Namely, we study the flow in a box with periodic boundary conditions driven by a constant imposed mean temperature gradient. The case of small Prandtl number and both the magnetic field and temperature gradient in vertical direction is consid作者: 舊石器時(shí)代 時(shí)間: 2025-3-23 09:17 作者: 缺乏 時(shí)間: 2025-3-23 13:25
