The Finite Volume Element Method for Time Fractional Generalized Burgers’ Equation
Fractal and FractionalIn this paper, we use the finite volume element method (FVEM) to approximate a one-dimensional, time fractional generalized Burgers’ equation. We construct the fully discrete finite volume element scheme for this equation by approximating the time ...

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Analysis of stabilized finite volume method for poisson equation
Mathematical Modelling and Analysis, 2013 In this work, we systematically analyze a stabilized finite volume method for the Poisson equation. On stating the convergence of this method, optimal error estimates in different norms are obtained by establishing the adequate connections between the ...

Discretization of continuum physics – a comparison of numerical methods from a physical point of view; pp. 145–154 [PDF]
Proceedings of the Estonian Academy of Sciences, 2008 For numerical calculations in continuum physics partial differential equations and the space-time are discretized. This can be done in different ways. Common approaches are finite difference methods and finite element methods, more rarely finite volume ...

Hybrid finite-volume–finite-element scheme for 3D simulation of thermal plasma arc configuration
AIP AdvancesThe plasma dynamics in a three-dimensional free-burning arc configuration are studied using an iterative hybrid finite-volume–finite-element scheme. In this scheme, Navier–Stokes equations are solved with a classical finite volume approach.
