  We present 4 model series of the CODEX dynamical opacity-sampling models of
Mira variables with solar abundances, designed to have parameters similar to
$o$ Cet, R Leo and R Cas. We demonstrate that the CODEX models provide a clear
physical basis for the molecular shell scenario used to explain interferometric
observations of Mira variables. We show that these models generally provide a
good match to photometry and interferometry at wavelengths between the
near-infrared and the radio, and make the model outputs publicly available.
These model also demonstrate that, in order to match visible and infrared
observations, the Fe-poor silicate grains that form within 3 continuum radii
must have small grain radii and therefore can not drive the winds from O-rich
Mira variables.
