  Flarix is a radiation-hydrodynamical (RHD) code for modeling of the response
of the chromosphere to a beam bombardment during solar flares. It solves the
set of hydrodynamic conservation equations coupled with non-LTE equations of
radiative transfer. The simulations are driven by high energy electron beams.
We present results of the Flarix simulations of a flaring loop relevant to the
problem of continuum radiation during flares. In particular we focus on
properties of the hydrogen Balmer continuum which was recently detected by
IRIS.
