dc.descriptionArtificial viscosity is needed in Smooth Particle Hydrodynamics to prevent interparticle penetration, to allow shocks to form and to damp post shock oscillations. Artificial viscosity may, however, lead to problems such as unwanted heating and unphysical solutions. A modification of the standard artificial viscosity recipe is proposed which reduces these problems. Some test cases discussed.
dc.descriptionSeven pages and 17 figures, accepted for publication in A&A main journal. (Here a latex version is included, and the figures hopefully more easy to print.)
