The Dynamical Interstellar Medium: Insights from Numerical Models
  Numerical models of the dynamical interstellar medium show that interactions between structures such as supernova remnants and superbubbles are more important than the structures themselves in determining the behavior of the ISM. I review the techniques and conclusions of recent global models, focussing on what they tell us about the formation of star-forming giant molecular clouds.
