gyre_in_mesa_spb

This test case checks the implementation of GYRE in MESA for a 5 Msun, Z=0.02 metallicity, model evolving from the zero-age main sequence to core hydrogen depletion; a slowly pulsating B-type star (SPB) stellar model.

This test case has 2 parts.

Part 1 (inlist_zams) builds a 5 Msun, Z=0.02 metallicity, pre-main sequence model and evolves it to the main sequence.
Part 2 (inlist_gyre_in_mesa_ms) continues the evolution until the central hydrogen mass fraction drops below 1e-2. During the evolution the run_star_extras.f90 calls GYRE, processes the GYRE output, and searches for a non-radial g-mode frequency of 7e-6 Hz (7 microHz). Close matches to this target frequency are reported in the terminal:
