Mass fractions, temperature, and density profiles (top three panels) at oxygen depletion and central temperature – central density evolutionary track (bottom panel) from ZAMS to core oxygen depletion for the M_ZAMS = 30 M_⊙ test case with the V-dJ algorithm and η = 1.0. We run the test case at the standard spatial resolution (Δ ≡mesh_delta_coeff=1.0, dashed lines) and twice that resolution (Δ ≡mesh_delta_coeff=0.5, solid lines).
