Planets and stars are often capable of generating their own magnetic fields. This occurs through dynamo processes occurring via turbulent convective stirring of their respective molten metal-rich cores and plasma-based convection zones. Present-day n

An invariant domain preserving arbitrary Lagrangian-Eulerian method for solving non-linear hyperbolic systems is developed. The numerical scheme is explicit in time and the approximation in space is done with continuous finite elements. The method is

International audience; In this paper, we investigate the approximation of a diffusion modelproblem with contrasted diffusivity for various nonconformingapproximation methods. The essential difficulty is that the Sobolevsmoothness index of the exact

We introduce a (linear) positive and asymptotic-preserving method for solving the one-group radiation transport equation. The approximation in space is discretization agnostic: the space approximat...
This paper is concerned with the approximation of the compressible Euler equations supplemented with an arbitrary or tabulated equation of state. The proposed approximation technique is robust, formally second-order accurate in space, invariant-domai

International audience; We introduce a technique that makes every explicit Runge--Kutta (ERK) time stepping method invariant-domain preserving and mass conservative when applied to high-order discretizations of the Cauchy problem associated with syst
