Helioseimology, the study of solar oscillations, has made a profound impact on our understanding of the structure and dynamics of the sun and is our only direct observational probe into the solar interior. By providing tests of helioseismic inversion methods using simulated oscillation data, we hope to improve the quantitative soundness of those helioseismic methods. Here, we present a numerical method for the simulation of the acoustic propagation equations in the full solar body. The numerical code is able to propagate linear waves with hight accuracy, i.e. with low dissipation, weak artificial reflections, accurate phase speeds, and coverage of the frequencies and wavelengths of interest. To accomplish these requirements, spherical harmonics are used in the angular directions and B-splines are used in the radial direction. B-splines allow arbitrary spacing of the radial mesh points and the dropping of high spherical modes deep in the interior where they do not propagate.
