Most of the recent visualisation work I have done with my collaborators can be found on the Cosmic Defects YouTube or Vimeo channels. I plan to write more about those soon. In the meantime, however, here are some older visualisations I made over the years.
I mostly use VisIt to create movies and 3D plots of my work.
This movie shows the fluid kinetic energy of a coupled field-fluid simulation of a first-order phase transition in the early universe. You can read the original paper on the arxiv or at the journal's website
