v0.8.4 Updating version number before breaking the i/o interface.Release v0.8.4
- SWIFT does not compile with FOF switched on by default any more to save memory.
- The EAGLE BH model now includes merging and swallowing of gas.
- The anarchy hydro models now features improvements for the diffusion.
- SWIFT comes with a better random number generator that allows probability of <10^9 to be sampled correctly.
-
v0.8.3 Bumped the version number following the addition of the FOF and black holes seeding.Release v0.8.3
- SWIFT now contains a Friends-Of-Friends halo identification code.
- SWIFT-FOF can be run as a stand-alone executable to post-process snapshots.
- SWIFT can run FOF on-the-fly to seed black hole particles following the EAGLE model.
- The 'Default' hydro scheme has been modified to be closer to the PHANTOM code. The code still compiles with Gadget2-SPH as a default scheme.
- Meta-data about the units of the fields written to snapshots have been added as HDF5 attributes.
