I'm making a pre-release of GYRE 5.0, to allow people to try out the
new functionality and see what works/doesn't. There have been many
changes since release 4.4; some of the highlights are as follows:
- The adiabatic (gyre_ad) and non-adiabatic (gyre_nad) executables
have been merged into a single executable (gyre), which handles both
adiabatic and non-adiabatic cases. To enable the latter, set the
'nonadiabatic' parameter in the &osc namelist to .TRUE. - There are now separate output namelists for adiabatic (&ad_output)
and non-adiabatic (&nad_output) data, allowing both (or neither) to
be written. - Rossby waves can now be modeled; see the example in
test/nad/mesa/spb-rossby for a simulation of the unstable mixed
Rossby-gravity modes discussed in Townsend (2005, MNRAS, 364, 573). - Stellar models with density discontinuities are now
supported. These discontinuities are flagged in the model by double
points --- two points having the same radius value, but different
density (and other) values. As of release r8118, MESA can output such
models --- see the 'add_double_points_to_pulse_info' and
'double_point_dlnrho_threshold' controls for more details. - There have been significant changes in how grids are specified;
rather than a sequence of &shoot_grid and &recon_grid namelists, now
GYRE uses a single &grid namelist. - There is now full support for relocating boundaries away from the
surface and/or center of the star.
safe to upgrade (modulo the fact that namelist files may need to be
updated). However, the documentation is lagging behind a bit -- I'm
updating it in a piecemeal fashion, so there may be some gaps. Download the pre-release from here:

Please post any problems to the forums, so I can look into
them in a timely manner.
