Primordial Black Holes is currently considered a candidate for the dark matter. Still, to give realistic and reliable predictions about their production and abundance, we need to accurately infer the initial conditions that can lead those black holes to be procured. In that sense, numerical simulations of PBH formation are generally essential. In this talk, I will describe how to accurately infer these conditions in different scenarios, starting from the standard case of PBH formation from a radiation fluid to move later to PBH production from vacuum bubbles generated during inflation. I will also describe scenarios where a time-dependent equation of state can play a crucial role, like the QCD crossover or from physics beyond the Standard Model, and its connection with scalar induced gravitational waves. Finally, I will discuss some ongoing research regarding non-standard configurations of the gravitational collapse.
