  In recent years, it has become clear from multidimensional simulations that
the outcome of deflagrations depends strongly on the initial configuration of
the flame. We have studied under which conditions this configuration could
consist of a number of scattered, isolated, hot bubbles. Afterwards, we have
calculated the evolution of deflagrations starting from different numbers of
bubbles. We have found that starting from 30 bubbles a mild explosion is
produced M(Ni56)=0.56 solar masses, while starting from 10 bubbles the star
becomes only marginally unbound (K = 0.05 foes).
