Scientific paper

We present preliminary results of a parametric study regarding smoothed particle hydrodynamic simulations of nodal and/or apsidal superhumps in cataclysmic variable systems. We show disk energy production (i.e., ``light'') curves and their associated Fourier transforms. The simulations are fully three-dimensional. The simulation system secondary-to-primary mass ratio q=M2/M1 spans the full range of observed apsidal superhump values (0.03 < q < 0.35). We compare our simulation results with observations and analytical expressions.
