Analysis and optimization of inner products for mimetic finite difference methods on a triangular grid

Autor: Mikhail Shashkov, Victor G. Ganzha, Richard Liska

Publikováno v: Mathematics and Computers in Simulation. 67:55-66

The support operator method designs mimetic finite difference schemes by first constructing a discrete divergence operator based on the divergence theorem, and then defining the discrete gradient operator as the adjoint operator of the divergence bas

Stability investigation of Runge–Kutta schemes with artificial dissipator on curvilinear grids for the Euler equations

Autor: Evgenii V. Vorozhtsov, Victor G. Ganzha

Publikováno v: Mathematics and Computers in Simulation. 58:1-35

By using the Fourier method we study the stability of a three-stage finite volume Runge–Kutta time stepping scheme approximating the 2D Euler equations on curvilinear grids. By combining the analytic and numeric stability investigation results we o

Application of Computer Algebra Systems for Stability Analysis of Difference Schemes on Curvilinear Grids

Autor: Victor G. Ganzha, Evgenii V. Vorozhtsov

Publikováno v: Journal of Symbolic Computation. 28:401-433

The paper deals with problems arising in the application of the computer algebra systems for the symbolic–numeric stability analysis of difference schemes and schemes of the finite-volume method approximating the two-dimensional Euler equations for
