HBT+

New implementation of HBT in C++ . This is the hybrid MPI/OpenMP parallelized version. Check the Hydro branch for a pure OpenMP version.

Documentation is available on the wiki.

About

This HBT+ version is compatible with SWIFT outputs, and was originally forked from the following branch. Since then, a number of additions enhancing the capabilities of HBT, as well as how it interfaces with SWIFT-based data outputs have been added.

Summary of additions/changes:

• Ability to specify which particle types to use as tracers of which FoF group hosts a subgroup/track, via the TracerTypeParticles parameter.
• Ability to specify two different gravitational softening values, reflecting the commonplace use in cosmological simulations of a comoving and maximum physical softening values: SofteningHalo and MaxPhysicalSofteningHalo, respectively.
• Automatic reading of gravitational softenings from SWIFT outputs, preventing the accidental use of incorrect values.
• Parameters.log file now groups the values of related parameters together.
• Compile-time git version information printed and saved to catalogues.

NOTE: these are currently under development, and so caution is advised.
