The structural method for Ordinary Differential Equations
S. Clain, M. T. Malheiro, G. J. Machado +1
We design and analyse a new numerical method to solve ODE system based on the structural method. We compute approximations of solutions together with its derivatives up to order $K…

a posteriori stabilized sixth-order finite volume scheme with adaptive stencil construction -- Basics for the 1D steady-state hyperbolic equations
Gaspar J. Machado, Stéphane Clain, Raphaël Loubère
We propose an adaptive stencil construction for high order accurate finite volume schemes aposteriori stabilized devoted to solve one-dimensional steady-state hyperbolic equations.…

An a posteriori strategy for adaptive schemes in time and space
Maria T. Malheiro, Gaspar J. Machado, Stéphane Clain
A nonlinear adaptive procedure for optimising both the schemes in time and space is proposed in view of increasing the numerical efficiency and reducing the computational time. The…
