In parallel with the tremendous increase in high-resolution observations of young protostars using the latest interferometers, significant progress has been made over the last ten years in our understanding of disk formation, outflows and protostars, thanks to multidimensional numerical simulations. Today, numerical experiments run on supercomputers and achieve unprecedented numerical resolution and temporal evolution. Using the results of recent 3D radiation magnetohydrodynamics simulations, I will review our current understanding of the formation and evolution of the protostellar disk, outflow and protostar through the different phases and scales of low- and high-mass dense core collapse. I will show to what extent the results of numerical experiments can address the fundamental problems of angular momentum and magnetic flux conservation. Finally, I will detail the questions still open and give some perspectives on the next generation of numerical experiments.
