Observations of transneptunian objects show a large fraction of binary pairs with components of similar size and colour. Previous work has shown that the gravitational collapse of a pebble cloud is an efficient mechanism for producing such systems. In this talk I will presents simulations of gravitational collapse of a pebble cloud using the PENCIL-Code considering different particle Stokes numbers. I will describe the setup of the simulations highlighting some of the important considerations. The results are compared to N-body simulations of cloud collapse and observations.
