  Ellerman bombs (EBs) seem to be a part of a whole spectrum of phenomena that
might have the same underlying physical mechanism, but with observed
characteristics which pose a considerable challenge to models. The aim of this
study is to investigate whether the proposed mechanism, applied to the
circumstances of EBs, produce the observed characteristics. For this, realistic
3D MHD simulations are used. Two different cases are presented: the quiet Sun
and an active region. Both runs confirm that EB-like brightenings coincide with
hot and dense plasma which is in agreement with predictions of 1D and 2D
modellings. The simulated EB-like phenomena assume the observed flame-like
form, which depends on the complexity of the ongoing reconnection and the
viewing angle. At the layers sampled by H$\alpha$-wings, near temperature
minimum and below, the magnetic field topology seem to be always the same. The
field lines there trace the base of the current sheet and the reconnected
$\cap$-loops. So, the EB features are caused by reconnection of strong-field
patches of opposite polarity in the regions where the surface flows are the
strongest. The weakest cases among them can be reproduced quantitatively by the
current simulations.
