Some remarks on discretisation of spatially invariant systems
The paper deals with discretisation of 2-D spatially invariant systems. Three different discretisation schemes are used ? Tustin?s approximation, backward difference scheme and Crank-Nicolson discretisation

Electromagnetic Analysis of Nanoscale Heterogeneity - The Domain-Integrated Perspective
of inhomogeneity may render the traditional discretisation of such topologies problematic. A new discretisation scheme that is much better matched to these topologies is proposed. The scheme involves a more adequa...

Application of compact finite-difference schemes to simulations of stably stratified fluid flows
ofthe compact finite-difference discretisations introduced in paper [S.K.Lele 1992]. The numerical scheme itself folows the principle of semi-discretisation, with high order compact discretisation in space, while ...

An implicit discontinuous Galerkin scheme for a numerical solution of transonic flow problems
This study is concerned with an implementation of the discontinuous Galerkin finite element method (DGFEM) combined with an appropriate implicit scheme for the spatial discretisation, has the advantage of being conservative and robu...

An energy-conserving time-discretisation scheme for poroelastic media with phase-field fracture emitting waves and heat
. The fractional-step Crank-Nicolson-type time discretisation is devised to decouplenthe system in a way so that the energy is conserved even in the discrete scheme. The numerical stability of such a scheme is shown, and al...

Oscillation-free Computation Homogenisation Scheme with Quasilinear Complexity
The proposed method combines the anisotropic Laplacian preconditioning, used in the Fourier-Galerkin method, with the finite element discretisation on a regular pixel/voxel grid. The piece-wise polynomial approximation avoids spurious oscill...

Finite Volume WLSQR Scheme and Its Applications to Transonic Flows
This article describes the development of a high order numerical method for the solution of compressible transonic flows. The discretisation in space is based on the standard finite volume method of Godunov's type. A higher order of accuracy...
