On the immersed boundary method: Finite element versus finite volume approach

Computers & Fluids, 2012
A projection approach is presented for the coupled system of time-dependent incompressible Navier-Stokes equations in conjunction with the Immersed Boundary Method (IBM) for solving fluid flow problems in the presence of rigid objects not represented by the underlying mesh. The IBM allows solving the flow for geometries with complex objects without the

Fundamentals of Finite Element and Finite Volume Methods

2018
There are three distinct methods of numerical solution techniques: finite difference, finite volume and finite element methods. The purpose in each is to convert the differential equations into algebraic equations. The main differences between the three methods are associated with the way the differential equations are converted to algebraic equations.

The finite volume element method for a parameter identification problem

Journal of Ambient Intelligence and Humanized Computing, 2014
In this paper we use finite volume element method to solve a parameter identification problem of parabolic equations with overspecified-data. We provide the numerical scheme of the unknown function and control parameters and obtain the error estimates of approximate solution.

Finite Element and Finite Volume Methods

2009
In this chapter we consider finite element and finite volume discretisations of $$Lu\,: = - \varepsilon u'' - bu' + cu = f\,\,{\rm in}\,(0,1), \,\,\ u(0) = u (1) = 0,$$ with b ≥ β > 0. Its associated variational formulation is: Find \(u \in H_0^1 (0,1)\) such that $$a(u, v) = f(v)\,\,\, {\rm for\, all}\,\, v \in H_0^1 (0,1),$$ (5.2 ...
