Title: GANDALF - Graphical Astrophysics code for N-body Dynamics And Lagrangian Fluids,
Abstract: GANDALF is a new hydrodynamics and N-body dynamics code designed for
investigating planet formation, star formation and star cluster problems.
GANDALF is written in C++, parallelised with both OpenMP and MPI and contains a
python library for analysis and visualisation. The code has been written with a
fully object-oriented approach to easily allow user-defined implementations of
physics modules or other algorithms. The code currently contains
implementations of Smoothed Particle Hydrodynamics, Meshless Finite-Volume and
collisional N-body schemes, but can easily be adapted to include additional
particle schemes. We present in this paper the details of its implementation,
results from the test suite, serial and parallel performance results and
discuss the planned future development. The code is freely available as an open
source project on the code-hosting website github at
this https URL and is available under the GPLv2
license.
