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 relativistic magnetohydrodynamics (3DRMHD) 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
