Tree-based solvers for adaptive mesh refinement code FLASH -- IV: An X-ray radiation scheme to couple discrete and diffuse X-ray emission sources to the thermochemistry of the interstellar medium
Brandt A. L. Gaches, Stefanie Walch, Richard Wünsch +1
X-ray radiation, in particular radiation between 0.1 keV and 10 keV, is evident from both point-like sources, such as compact objects and T-Tauri young stellar objects, and extende…
Tree-based solvers for adaptive mesh refinement code FLASH -- III: a novel scheme for radiation pressure on dust and gas and radiative transfer from diffuse sources
A. Klepitko, S. Walch, R. Wünsch +3
Radiation is an important contributor to the energetics of the interstellar medium, yet its transport is difficult to solve numerically. We present a novel approach towards solving…
A Discontinuous Galerkin Solver in the FLASH Multi-Physics Framework
Johannes Markert, Stefanie Walch, Gregor Gassner
In this paper, we present a discontinuous Galerkin solver based on previous work by Markert et al. (2021) for magneto-hydrodynamics in form of a new fluid solver module integrated…
Tree-based solvers for adaptive mesh refinement code FLASH -- II: radiation transport module TreeRay
Richard Wünsch, Stefanie Walch, František Dinnbier +5
The treatment of radiative transfer with multiple radiation sources is a critical challenge in simulations of star formation and the interstellar medium. In this paper we present t…
Tree-based solvers for adaptive mesh refinement code FLASH - I: gravity and optical depths
Richard Wünsch, Stefanie Walch, František Dinnbier +1
We describe an OctTree algorithm for the MPI-parallel, adaptive mesh-refinement code {\sc FLASH}, which can be used to calculate the gas self-gravity, and also the angle-averaged l…
An improved sink particle algorithm for SPH simulations
D. A. Hubber, S. Walch, A. P. Whitworth
Numerical simulations of star formation frequently rely on the implementation of sink particles, (a) to avoid expending computational resource on the detailed internal physics of i…
