Comparison of the stellar structures of the initial models of the sim_k and sim_m simulation. Results for the 3-equation model and the MLT model are shown in yellow and green, respectively. We show the temperature, pressure, hydrogen and density profiles from top left to lower right. The difference between the two initial models is shown in the small panels below the profiles. The initial thermal stratifications can be found in Fig. 1. We note that the green and yellow lines largely overlap due to the similarity of the initial stellar models.
