,Numerical Solution of the Neutron Diffusion Equation—Adaptive Concepts in Time and Space,cussed and closely related adaptive concepts are presented. For a 2-D model problem some numerical results are given. Finally, the use of adaptive hybrid mixed finite element discretizations is considered for 3-D calculations on a rectangular geometry and an implementational concept is shortly presented.可用 发表于 2025-3-23 16:13:37
Coupling of a global coarse discretization and local fine discretizations,e effect of the local defect correction step the local discretization error is discussed. If the defect correction step is performed at the correct places then the accuracy of the resulting approximation is in agreement with the resolution of the composite grid. Numerical examples illustrate the theoretical insights.百灵鸟 发表于 2025-3-23 22:02:39

A Numerical Scheme for Stress Waves at a Fluid-Solid Interface,quid side is coupled with a Godunov-type method for elastic-plastic waves in solids. Applying the contact conditions an interative convergent scheme is obtained. Numerical results are presented for a plane problem with a cylindrical shock wave developing in the liquid.巨硕 发表于 2025-3-24 04:11:05

Coupled Geometric Modelling for the Analysis of Groundwater Flow and Transport in Fractured Rock,al elements for fracture planes). These methods are based on the Delaunay triangulation. Therefore they can be applied to arbitrary convex domains consisting of a set of convex subdomains surrounded by fracture planes.panorama 发表于 2025-3-24 11:48:26

Conference proceedings 1995oupling of subsystems can be generated by the numerical solution technique. General examples of the latter kind are the domain decomposition (see p. 128) or subspace decomposition (p. 117). The local defect correction method couples different discretizations of the same problem in order to improve t
