VINE

VINE is a particle based astrophysical simulation code. It uses a tree structure to efficiently solve the gravitational N-body problem and Smoothed Particle Hydrodynamics (SPH) to simulate gas dynamical effects. The code has been successfully used for a number of studies on galaxy interactions, galactic dynamics, star formation and planet formation and given the implemented physics, other applications are possible as well.

Features of the Code include:

• Binary (‘Press’) tree structure for calculation of gravitational forces by multipole expansion
• SPH for gas dynamics
• Individual particle time steps
• Leapfrog integrator and 2nd order Runge-Kutta integrator implemented
• Periodic boundary conditions using Ewald’s method
• Point masses, to be used e.g. as sink particles in star formation
• Optional use of GRAPE hardware.
• Written in standard Fortran-95
• Parallelized for shared memory architectures using OpenMP.
• Very modular code structure, easy to include additional modules
