Convergence behavior for MALI and multigrid for three-level Ca ii (left-hand panel) and hydrogen atom (right-hand panel) for atmosphere Model 1. The computation was performed with three grids, full-weighting restriction, and trilinear interpolation. For three-level Ca ii we used ν1 = 2, ν2 = 2, ν3 = 32 and for H i  we used ν0 = 15,ν1 = 2, ν2 = 25, ν3 = 32.
