3.0 release

Post by rhtownsend » Thu Feb 27, 2014 11:45 pm

I'm pleased to announce the release of version 3.0 of GYRE.

New features in this release include:
  • New op_type option, CREATE_MIDPOINT, in &shoot_grid and &recon_grid namelists. This places grid points at the midpoints of the input grids. This option is key to producing 'good' eigenfunctions when performing non-adiabatic calculations
  • Renamed the &coeffs namelist to &model, and the coeffs_type parameter to &model_type
  • Added new &constants namelist, to allow overriding of physical constants
  • New output items: f_T, f_g, psi_T and psi_g, being the non-adiabatic coefficients defined by Dupret et al. (2003). These are evaluated at x = x_ref
  • New &osc parameter: x_ref
  • Added xi_r_ref and xi_h_ref output items, which give the displacement eigenfunctions at x = x_ref
  • Added warnings when scan frequency range goes above/below atmospheric cutoffs
The most important new feature is that well-behaved non-adiabatic eigenfunctions can now be calculated by using a CREATE_MIDPOINT reconstruction grid.
