An operator splitting method for atmospheres with shocks
Abstract
We develop a fast operator splitting (OS) method to solve spectral line radiative transfer problems in time-dependent hydrodynamic computations with shock discontinuities, assuming complete redistribution. The convergence properties and the results obtained with our method are compared with results obtained using a modified core-saturation method and with the {LAMBDA}-iteration. We find that our operator splitting method is robust, accurate and fast.
