3 Simulation Results 23 blocks is surrounded by a layer of guard cells that are filled either by exchanging data from sibling meshes at the same level or by interlevel interpolation from coarse to fine meshes. 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.
