.. _gyre_in_mesa_spb: **************** gyre_in_mesa_spb **************** .. tags:: star, gyre, asteroseismology, g-mode, nonradial-pulsation, spb, intermediate-mass, main-sequence 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).
