  We simulate the production of vortices in a first order phase transition at
finite temperature. The transition is carried out by randomly nucleating
critical bubbles and the effects of thermal fluctuations (which could be
relevant for vortex production) are represented by randomly nucleating
subcritical bubbles. Our results show that the presence of subcritical bubbles
suppresses vortices with clear and prominent profiles, though net number of
vortices is consistent with theoretical estimates. We also determine the
typical speed of vortices arising due to randomness associated with the phase
transition to be about 0.5.
