Query: Self-consistent 3D radiative MHD simulations of coronal rain formation
  and evolution   Coronal rain consists of cool and dense plasma condensations formed in
coronal loops as a result of thermal instability. Previous numerical
simulations of thermal instability and coronal rain formation have relied on
artificially adding a coronal heating term to the energy equation. To reproduce
large-scale characteristics of the corona, using more realistic coronal heating
prescription is necessary. We analyse coronal rain formation and evolution in a
3-dimensional radiative magnetohydrodynamic simulation spanning from convection
zone to corona which is self-consistently heated by magnetic field braiding as
a result of convective motions. We investigate the spatial and temporal
evolution of energy dissipation along coronal loops which become thermally
unstable. Ohmic dissipation in the model leads to the heating events capable of
inducing sufficient chromospheric evaporation into the loop to trigger thermal
instability and condensation formation. The cooling of the thermally unstable
plasma occurs on timescales comparable to the duration of the individual
impulsive heating events. The impulsive heating has sufficient duration to
trigger thermal instability in the loop but does not last long enough to lead
to coronal rain limit cycles. We show that condensations can either survive and
fall into the chromosphere or be destroyed by strong bursts of Joule heating
associated with a magnetic reconnection events. In addition, we find that
condensations can also form along open magnetic field lines.
