Calculating the nucleosynthetic yields from large-scale hydrodynamical simulations of astrophysical phenomena (such as Type Ia supernovae) involves the post-processing of tracer particles that track the individual fluid elements in the object. The number of tracer particles in the simulation can be on the order of hundreds of thousands; however, the question of the number of tracer particles needed to accurately predict output of the nucleosynthesis has not been addressed. We present statistics that answer the question of how many tracer particles are needed and offer guidelines for those running particle enabled simulations, specifically in the context of turbulent combustion in Type Ia supernova settings.
