[Mesa-users] Setting a constant dm for cells within a specific region of the star

[Rob Farmer]

Hi,
There is no ability in mesa to exactly specify the cell size. However for
accretion we do switch how we split the cells based on either mass or q in
the surface layers.

See the controls in this section
https://docs.mesastar.org/en/release-r21.12.1/reference/controls.html#max-logt-for-k-below-const-q
and the discussion in section 7 of
https://ui.adsabs.harvard.edu/abs/2015ApJS..220...15P/abstract
