Abstract
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.
