THC: a new high-order finite-difference high-resolution shock-capturing code for special-relativistic hydrodynamics

Radice, David, Rezzolla, Luciano

Understand

We present THC: a new high-order flux-vector-splitting code for Newtonian and special-relativistic hydrodynamics designed for direct numerical simulations of turbulent flows.

  • Our code implements a variety of different reconstruction algorithms, such as the popular weighted essentially non oscillatory and monotonicity-preserving schemes, or the more specialised bandwidth-optimised WENO scheme that has been specifically designed for the study of compressible turbulence.
  • We show the first systematic comparison of these schemes in Newtonian physics as well as for special-relativistic flows.
  • In particular we will present the results obtained in simulations of grid-aligned and oblique shock waves and nonlinear, large-amplitude, smooth adiabatic waves.
