Code comparison problem within the EU planet network

On this page, we present some results of our SPH simulations of planet-disc interactions.
For details about the main setup see code comparison problem home page.
This work was done by Roland Speith and Christoph Schäfer using ParaSPH, firstly developed and maintained by Michael Hipp.

ParaSPH is a parallelized (using MPI) smooth(ed) particle hydrodynamics code for solving the system of hydrodynamic equations for compressible and viscous fluids. We follow the approach by Flebbe et al. and solve the Navier-Stokes equation including the entire viscous stress tensor. In contrast to the usual approach of an artificial viscosity by Gingold and Monaghan we use an artificial bulk viscosity.
This allows for an accurate treatment of the physical shear viscosity. Additionally we use the xsph device to prevent particles from mutual penetration. Please see ads-link for details about the code. Units used in these simulations: Mass in solar mass, length in astronomical units, time in seconds.
