Release notes:

  • fargo3d-1.2 (Fri Dec 11 2015):
    • Fixed a bug that could lead to random crashes on 2D and 1D runs on GPUs.
    • Fixed a bug introduced in version 1.1 with the +S command line switch.
    • Implemented alpha viscosity in cylindrical and spherical setups.
    • Implemented polytropic equation of state.
    • Implemented GPU reductions based on warp shuffle for >= 3.5 architectures. Requires build option WARPSHUFFLE.
    • Merging output files from different processes is now the default. The execution flag -m is kept for backward compatibility. In order to keep the different files separated, use the -k flag.
    • Implemented binary setup. Check manual for details.
  • fargo3d-1.1:
    • Implemented geometrical source terms on the magnetic tension in curvilinear coordinates.
    • Implemented magnetic pressure gradient in spherical coordinates (was missing).
    • Implemented geometrical source terms on the curl of magnetic field (current, used when physical resistivity is present).
    • Implemented new variable NSNAP (see manual), which allows to select the fields written to the disk in order to oversample some of them (e.g., for animations).
    • Solved a race condition that could arise during compilation.
    • Corrected misprints and updated manual.
  • fargo3d-1.0:
    • Corrected a bug that gave incorrect domains with multiple processes and a log scaling of zones radii.
    • Corrected a bug that led to random crashes upon run start when using multiple GPUs.
    • Corrected a miscentering of wave damping boundary conditions on Vz in file stockholm.c.
    • Corrected a bug that led to wrong wave damping conditions when the frame had a variable angular velocity (typically when tracking a migrating planet). The change of angular velocity is now fully taken into account in stockholm.c
    • Corrected a bug that yielded incorrect change of azimuthal velocity when the frame had a time varying angular velocity, in spherical coordinates (in file correct_vtheta.c)
    • Resolved an issue with the tracking of the guiding center of a planet with an inclined orbit.
    • The resistivity arrays are now filled prior to evaluating the maximum time step allowed by that CFL condition.
    • When a calculation includes one or several planets, the files orbit[i].dat, planet[i].dat and bigplanet[i].dat are now written, as in the former FARGO code. Their content is however different (see manual).
    • Added the possibility to remove the azimuthally averaged surface density prior to the torque evaluation (see Baruteau & Masset 2008, ApJ, 678, 483). The user simply needs to add the BM08 flag in the opt file (FARGO_OPT += -DBM08).
    • Added some new command line switches (-o, to manually overwrite some variables of the parameter file, +S, to stretch azimuthally a simulation initially ran with low resolution in azimuth, -# and +#, to run arrays of calculations). See the manual for more details.
    • Added new setups (p3diso, p3disof which correspond to 3D spherical setups with an isothermal EOS of a Keplerian disk with an embedded planet; the former assumes equatorial symmetry and simulates the half the disk above the equatorial plane, whereas the latter considers the full disk).
    • Added new tests to the test_suite
    • Added more flexibility to spawn runs on clusters of GPUs (+D flag)
    • Added history files in $HOME/.fargo3drc
    • Modified the documentation
    • Cosmetic changes (possibility to define the first planet’s mass in the parameter file with PLANETMASS, possibility to rescale all radii -planets and mesh- with one optional parameter, ORBITALRADIUS).
  • fargo3d-0.9:
    • first public release of the code
