# gyre_tides

The gyre_tides frontend calculates the response of a stellar model to tidal forcing by a orbiting point-mass companion. The general flow of execution is outlined in the chart to the right. After reading the namelist input file and the model, gyre_tides loops over &tide namelist groups, processing each in turn.

For a given group, gyre_tides evaluates the response to partial tidal potentials spanning a range of harmonic degrees $$\ell$$, azimuthal orders $$m$$ and Fourier harmonics $$k$$ (see the Linearized Equations section). With each partial potential, the response wavefunctions and other data are optionally written to a detail file. At the end of the run, response data from all partial responses (across all &tide groups) are optionally written to a summary file.

The table below lists which namelist groups, and in what number, should appear in namelist input files for gyre_tides.
