Hero I use the MHD code, FLASH, from the University of Chicago ASCI Center for Astrophysical Thermonuclear Flashes, to simulate initial two-dimensional simple models of accretion streams in magnetic CVs. These models explore the evolution of inflowing material for two white dwarf masses; 0.5M⊙ and 0.9M⊙. It is seen that a discontinuity forms at a height of 6.1 X 108 cm above the white dwarf ‘surface’ for MWD = 0.5M⊙ and at 1.6 X 109 cm for MWD = 0.9M⊙. These models will be developed further with the ultimate goal of completing a three-dimensional model of magnetic accretion onto a WD surface.
