We review recent progress in understanding the hydrodynamics of compact binary mergers using relativistic smoothed particle hydrodynamics (SPH) codes. Recent results are discussed for both double neutron stars and black hole - neutron star binaries. The gravitational wave signals from these mergers contain a lot of information about the masses and radii of the stars and the equation of state of the neutron star fluid. For black hole - neutron star mergers, the final fate of the fluid and the gravitational wave emission depend strongly on the mass ratio and the black hole spin.
