3D GRMHD code RAISHIN

RAISHIN code is used a conservative finite volume shock-capturing schemes (Gudonov-type schemes) to solving the hyperbolic partial differential equations (PDE). This version of code is specialized for solving 3D ideal special & general relativistic magnetohydrodynamics (3DSRMHD/3DGRMHD) using 3D MPI parallelization.

Ability of RAISHIN code

  • Multi-dimension (1D, 2D, 3D)
  • Spacial & General relativity (metric is static)
  • Different coordinates (SRMHD: Cartesion, Cylindrical, Spherical and GRMHD: Boyer-Lindquist of non-rotating and rotating black hole)
  • Different spatial reconstruction schemes (7)
  • Different approximate Riemann solver schemes (4)
  • Different constrained transport schemes (3) or divergence cleaning scheme (1)
  • Different time advance schemes (2)
  • Using constant G-law and approximate Equation of State (Synge-type)
  • Parallelized by MPI
