Reducing the complexity of chemical networks via interpretable autoencoders
T. Grassi, F. Nauman, J. P. Ramsey +3
In many astrophysical applications, the cost of solving a chemical network represented by a system of ordinary differential equations (ODEs) grows significantly with the size of th…
A simple and efficient solver for self-gravity in the DISPATCH astrophysical simulation framework
J. P. Ramsey, T. Haugbølle, Å. Nordlund
We describe a simple and effective algorithm for solving Poisson's equation in the context of self-gravity within the DISPATCH astrophysical fluid framework. The algorithm leverage…
DISPATCH: A Numerical Simulation Framework for the Exa-scale Era. I. Fundamentals
Å. Nordlund, J. P. Ramsey, A. Popovas +1
We introduce a high-performance simulation framework that permits the semi-independent, task-based solution of sets of partial differential equations, typically manifesting as upda…
Radiation hydrodynamics including irradiation and adaptive mesh refinement with AZEuS. I. Methods
J. P. Ramsey, C. P. Dullemond
Aims. The importance of radiation to the physical structure of protoplanetary disks cannot be understated. However, protoplanetary disks evolve with time, and so to understand disk…
AZEuS: An Adaptive Zone Eulerian Scheme for Computational MHD
Jon P. Ramsey, David A. Clarke, Alexander B. Men'shchikov
A new adaptive mesh refinement (AMR) version of the ZEUS-3D astrophysical magnetohydrodynamical (MHD) fluid code, AZEuS, is described. The AMR module in AZEuS has been completely a…
