A Convergence Analysis of a Multistep Method Applied to an Advection-Diffusion Equation in 1-Dlas. The present study discusses the convergence of the method when applied to a convection-diffusion equation in 1-D. The convergence analysis conducted produced sufficient conditions for the consistency analysis and used the von Neumann analysis to demonstrate that the method is stable. Moreover,

The Influence of Reordering Algorithms on the Convergence of a Preconditioned Restarted GMRES Method preconditioned by three ILU-type preconditioners. This paper investigates the effect of 13 orderings on the convergence of the preconditioned GMRES solver restarted every 50 steps when applied to nine real large-scale nonsymmetric and not positive definite matrices. Specifically, this paper shows t

User-Friendly Expressions of the Coefficients of Some Exponentially Fitted Methodsllations and loss of precision. Usually the coefficients of an EF method are expressed in terms of ., where . is the frequency and . is the step size. Often, these coefficients exhibit a 0/0 indeterminate form when .. To avoid this feature we will use two sets of functions, called . and ., which hav

CFD Prediction of Retractable Landing Gear Aerodynamicshe mean flow around the landing-gear system including doors is simulated by using the Reynolds-averaged Navier-Stokes modelling approach, the governing equations being solved with a finite volume-based numerical technique. The computational grid is automatically adapted to the time-changing geometry

CFD Prediction of Aircraft Control Surfaces AerodynamicsThe virtual experiments are performed in operational conditions by resolving the mean turbulent flow field around a suitable model of the whole aircraft. The Reynolds-averaged Navier-Stokes modelling approach is used, where the governing equations are solved with a finite volume-based numerical tech
