3D MHD Mancha code:

  • Solves non-linear equations for perturbations
  • Magneto-static equilibrium is explicitly removed from the equations
  • 4th order central difference in space and 4th order Runge-Kutta in time
  • Stabilized by hyper-diffusive terms
  • PML absorption layer boundary conditions
  • Energy losses according to Newton cooling law
  • OPAL or ideal equation of state
  • MPI parallelized using domain decomposition
  • Written in Fortran 90
