In the calculation of the second-order accurate hyperbolic fluxes, linear interpolation is sufficient, while the diffusive fluxes require a quadratic interpolation. We employ the Berger–Oliger timestepping technique in which the timesteps are determined by the CFL condition imposed by the ideal MHD wave speeds and are computed at the finest level and then appropriately coarsened by the refinement ratio to determine the larger stable timestep for coarser levels. We maintain flux registers that are used during synchronization when disparate levels reach the same physical time.
