A Confined Flow over a Cylinder by the Finite Element and the Finite Difference Methods [PDF]

open access: yesEngineering and Technology Journal, 2011
The Finite element and the finite difference methods were applied to a confined flow over a cylinder. The values of velocity potential (F), the stream function (Y) and the velocity distribution are calculated by using a computer programs achieved by the ...

A Comparison of Finite Difference and Finite Volume Methods with Numerical Simulations: Burgers Equation Model

open access: yesComplexity, 2022
In this paper, we present an intensive investigation of the finite volume method (FVM) compared to the finite difference methods (FDMs). In order to show the main difference in the way of approaching the solution, we take the Burgers equation and the ...

Stabilized finite difference methods for the fully dynamic biot's problem

open access: yesMathematical Modelling and Analysis, 2013
This paper deals with the stabilization of the poroelasticity system, in the incompressible fully dynamic case. The stabilization term is a perturbation of the equilibrium equation that allows us to use central difference schemes to approximate the first

Application of finite-difference methods to parameter identification of agroecological models

open access: yesLietuvos Matematikos Rinkinys, 2001
A typical parameter identification problem arisen in agroecological modeling is described and a finite difference method to solve an appropriate inverse problem is proposed.

Computational methods for difference families in finite abelian groups

open access: yesSpecial Matrices, 2019
Our main objective is to show that the computational methods, developed previously to search for difference families in cyclic groups, can be fully extended to the more general case of arbitrary finite abelian groups.

Frequency‐dependent finite‐difference time‐domain method based on iterated Crank–Nicolson scheme

open access: yesElectronics Letters, 2023
The finite‐difference time‐domain (FDTD) method based on the iterated Crank–Nicolson (ICN) scheme is extended to a frequency‐dependent version. The Drude model is used to express a metal dispersion, which is incorporated into the iterated Crank–Nicolson ...

Comparison of the stability of discontinuous Galerkin and finite-difference methods

open access: yesLietuvos Matematikos Rinkinys, 2002
In this article we present stability analysis of two discrete schemes, which are used to solve a parabolic problem on adaptive nonstationary meshes. The influence of interpolation and projection errors is investigated.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?
