CVS info : $Header$ Cactus Code Thorn PadHydro Thorn Author(s) : Erik Schnetter Thorn Maintainer(s) : Erik Schnetter -------------------------------------------------------------------------- Purpose of the thorn: PadHydro is an SPH implementation that uses the Pad particle driver. TODO: Problem: Total energy is not conserved; kinetic energy rises, maybe exponentially so. Ideas: 1. spline kernel instead of cusp kernel 2. smaller error tolerance for Poisson solver 3. integrate energy to have a conservative formulation 4. different interpolator for the potential gradient 5. watch velocity of centre of mass 6. take potential derivative on the particles 7. make gravitational self-interactions conserve momentum
