HERACLES++: A multidimensional Eulerian code for exascale computing
Lou Roussel-Hard, Edouard Audit, Luc Dessart +2
Numerical simulations of multidimensional astrophysical fluids present considerable challenges. However, the development of exascale computing has significantly enhanced computatio…
A multi-dimensional, robust, and cell-centered finite-volume scheme for the ideal MHD equations
Pascal Tremblin, Rémi Bourgeois, Solène Bulteau +6
We present a new multi-dimensional, robust, and cell-centered finite-volume scheme for the ideal MHD equations. This scheme relies on relaxation and splitting techniques and can be…
Nonideal self-gravity and cosmology: the importance of correlations in the dynamics of the large-scale structures of the Universe
P. Tremblin
Inspired by the role of correlations in the statistical mechanics of nonideal self-interacting fluids, we suggest that unresolved sub-structures (i.e. correlations) have to be take…
Recasting an operator splitting solver into a standard finite volume flux-based algorithm. The case of a Lagrange-Projection-type method for gas dynamics
Rémi Bourgeois, Pascal Tremblin, Samuel Kokh +1
In this paper, we propose a modification of an acoustic-transport operator splitting Lagrange-projection method for simulating compressible flows with gravity. The original method…
Non-ideal self-gravity and cosmology: the importance of correlations in the dynamics of the large-scale structures of the Universe
P. Tremblin, G. Chabrier, T. Padioleau +1
Inspired by the statistical mechanics of an ensemble of interacting particles (BBGKY hierarchy), we propose to account for small-scale inhomogeneities in self-gravitating astrophys…
Radiative Rayleigh-Taylor Instability and the structure of clouds in planetary atmospheres
P. Tremblin, H. Bloch, M. González +5
Clouds are expected to form in a wide range of conditions in the atmosphere of exoplanets given the large range of possible condensible species. However this diversity might lead t…
Idealised 3D simulations of diabatically-forced Ledoux convection. Application to the atmosphere of hot rocky exoplanets
Simon Daley-Yates, Thomas Padioleau, Pascal Tremblin +2
We investigate the impact on convective numerical simulations of thermo-compositional diabatic processes. We focus our study on simulations with a stabilizing temperature gradient…
A high-performance and portable asymptotic preserving radiation hydrodynamics code with the M1 model
H. Bloch, P. Tremblin, M. González +2
Aims. We present a new radiation hydrodynamics code, called "ARK-RT" which uses a two-moment model with the M1 closure relation for radiative transfer. This code aims at being read…
A high performance and portable all-Mach regime flow solver code with well-balanced gravity. Application to compressible convection
T. Padioleau, P. Tremblin, E. Audit +2
Convection is an important physical process in astrophysics well-studied using numerical simulations under the Boussinesq and/or anelastic approximations. However these approaches…
Thermo-compositional diabatic convection in the atmospheres of brown dwarfs and in Earth's atmosphere and oceans
P. Tremblin, T. Padioleau, M. Phillips +12
By generalizing the theory of convection to any type of thermal and compositional source terms (diabatic processes), we show that thermohaline convection in Earth oceans, fingering…
