Geochemistry, Geophysics, Geosystems, Volume 25, Issue 2, February 2024.Abstract “Flip‐flop” detachment mode represents an endmember type of lithosphere‐scale faulting observed at almost amagmatic sections of ultraslow‐spreading mid‐ocean ridges. Recent numerical experiments using an imposed steady temperature structure show that an axial temperature maximum is essential to trigger flip‐flop faults by focusing flexural ...

An extension of A-stability to alternating direction implicit methods [PDF]
An alternating direction implicit (ADI) scheme was constructed by the method of approximate factorization. An A-stable linear multistep method (LMM) was used to integrate a model two-dimensional hyperbolic-parabolic partial differential equation ...

IET Microwaves, Antennas &Propagation, Volume 18, Issue 2, Page 59-72, February 2024.In this study, a systematic analysis of the error and computational complexity of the FDPE and SSPE methods for radio wave propagation modelling in tunnels is provided. Guidelines for the choice of their parameters are provided, and their performance is demonstrated through both numerical examples and experimental measurements in actual tunnel cases ...

Effect of Perpendicular Magnetic Field on Free Convection in a Rectangular Cavity
Sultan Qaboos University Journal for Science, 2015 The steady free convective flow of a viscous incompressible and electrically conducting fluid in a two-dimensional cavity in the presence of a magnetic field applied normal to the plane of the cavity is investigated. The side vertical walls of the cavity

Intermediate boundary conditions for LOD, ADI and approximate factorization methods [PDF]
A general approach to determining the correct intermediate boundary conditions for dimensional splitting methods is presented. The intermediate solution U is viewed as a second order accurate approximation to a modified equation.

Parallel algorithm for numerical solution of heat equation in complex cylindrical domain
Discrete and Continuous Models and Applied Computational Science, 2019 In this article we present a parallel algorithm for simulation of the heat conduction process inside the so-called pulse cryogenic cell. This simulation is important for designing the device for portion injection of working gases into ionization chamber ...
