Numerical Scheme

by Misun Min, Yong-ho Chin, Paul F. Fischer, Yong-chul Chae, Kwang-je Kim
"... We investigate the Fourier spectral time-domain simulations applied to the wake field calculations in twodimensional cylindrical structures. The scheme involves second-order explicit leap-frogging in time and the Fourier spectral approximation in space, which is obtained from simply replacing the sp ..."

Numerical Scheme of Magnetic Monopoles

by M. Affouf
"... Abstract: In this paper, we present a numerical method to compute the ’t Hooft-Polyakov static magnetic monopoles as an asymptotic limit of a coupled system of evolution equations. An efficient numerical scheme and its results will be presented. Key–Words: Monopoles, Yang-Mills-Higgs equations, Nume ..."

A Numerical Scheme For Dynamic . . .

by Lixia Yuan, et al. , 1998
"... This paper presents a numerical scheme for dynamic analysis of mechanical systems subjected to damping forces which are proportional to fractional derivatives of displacements. In this scheme, a fractional differential equation governing the dynamic of a system is transformed into a set of different ..."

Approximate Riemann Solvers, Parameter Vectors, and Difference Schemes

by P. L. Roe - J. COMP. PHYS , 1981
"... Several numerical schemes for the solution of hyperbolic conservation laws are based on exploiting the information obtained by considering a sequence of Riemann problems. It is argued that in existing schemes much of this information is degraded, and that only certain features of the exact solution ..."

Conservative numerical schemes for the Vlasov equation

by Francis Filbet, Pierre Bertr - J. Comput. Phys , 2001
"... A new scheme for solving the Vlasov equation using a phase space grid is pro-posed. The algorithm is based on the conservation of the flux of particles, and the distribution function is reconstructed using various techniques that allow control of spurious oscillations or preservation of the positivi ..."

of the positivity. Several numerical results are presented in two- and four-dimensional phase space and the scheme is compared with the semiLagrangian method. This method is almost as accurate as the semi-Lagrangian one, and the local reconstruction technique is well suited for parallel computation. c ° 2001

Numerical Solutions of the Euler Equations by Finite Volume Methods Using Runge-Kutta Time-Stepping Schemes

by Antony Jameson, Wolfgang Schmidt, Eli Turkel , 1981
"... A new combination of a finite volume discretization in conjunction with carefully designed dissipative terms of third order, and a Runge Kutta time stepping scheme, is shown to yield an effective method for solving the Euler equations in arbitrary geometric domains. The method has been used to deter ..."

A numerical scheme for impact problems

by Laetitia Paoli, Michelle Schatzman - I and II, SIAM Journal Numer. Anal , 2002
"... Abstract. We consider a mechanical system with impact and n degrees of freedom, written in generalized coordinates. The system is not necessarily Lagrangian. The representative point is subject to a constraint: it must stay inside a closed set K with boundary of class C 3. We assume that, at impact, ..."

numerical scheme which enables us to approximate the solutions of the Cauchy problem: this is an ad hoc scheme which does not require a systematic search for the times of impact. We prove the convergence of this numerical scheme to a solution, which yields also an existence result. Without any a priori
