Cataclysmic variable (CV) stars are close binary systems with typically a white dwarf primary accreting from a low-mass main-sequence secondary star. One useful technique to study these systems observationally is through time-series spectroscopy. A method by which synthetic line profiles can be produced using the CV modeling program FITDISK will be discussed. Because we compute the velocities and instantaneous energy dissipation ("luminosity") of all the particles in the simulation, we can synthesize line profiles as a function of simulation time. Methods used and results will be presented.
