[yt-users] ANN: Enzo 2.4 Release

[Nathan Goldbaum]

We are pleased to announce the release of version 2.4 of the Enzo code.
This is a periodic release that includes all changes committed to the Enzo
BitBucket repository since July 2013. This release contains some new
features and a number of enhancements and bugfixes.

Enzo now has bindings to version 1.0 of the grackle chemistry and cooling
library. Grackle is based on Enzo's own cooling and chemistry code and
includes updated rate and chemistry tables, as well a number of
enhancements and new features that are not available in Enzo's native
chemistry and cooling modules.

Enzo's solvers and physics modules have also seen improvements, including
updates for the GPU MHD solver, the FLD solver, and the MHD-CT solver, the
Jeans pressure floor, the Cen & Ostriker star particle, tracer particles,
and particle splitting.

There have also been a number of infrastructure improvements, including a
new progress meter script (which allows the user to monitor simulations
during runtime), updates for geometric refinement regions and the shear
refinement criterion, improved control over the frequency of hierarchy
rebuilds, updates for test problem initialization (which is now more memory
efficient), and improvements to the GalaxySimulation, KelvinHelmholtz, and
CosmologySimulation problem types. There is also a new rotating turbulent
sphere problem type.

There have also been a number of significant bugfixes, including several
that may increase the stability and efficiency of production multi-physics
simulations.

We urge all users to update to the latest version if they are using Enzo
2.3 or earlier. While one can obtain the release by downloading a tar file,
we strong encourage all users to use enzo from a clone of the mercurial
repository, which will facilitate reproducible work with the code.

On behalf of the Enzo collaboration,
