[Mesa-users] Diagram TRho - D

> If I understood well, the length of the line varies according to the
number of zones available in each simulation step, right? If so, is it
right to assume that the lower end corresponds to conditions at the surface
of the star and the upper one to those at the innermost part of the nucleus?

The length of the line depends on how the density and temperature of your
star varies over the model. The lower end would be zone 1, the outer most
point of your model, and the upper end zone nz, the inner most point of
your model.
