Abstract
We present simulations of magneto‐acoustic wave propagation in a magnetic, plane‐parallel stratified solar model atmosphere, employing the CO^5^BOLD‐code. The tests are carried out for two models of the solar atmosphere, which are similar to the ones used by Cally (2007) and Schunker & Cally (2006). The two models differ only in the orientation of the magnetic field. A qualitative comparison shows good agreement between the numerical results and the results from ray theory. The tests are done in view of the application of the present numerical code for the computation of energy fluxes of propagating acoustic waves into a dynamically evolving magnetic solar atmosphere. For this, we consider waves with frequencies above the acoustic cut‐off frequency (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
