I'm reading up a series of papers on hydrodynamical simulations for galaxies and cosmology. They keep mentioning things like "Lagrangian" or "pseudo-lagrangian" or "Eulerian". I tried looking it up on the internet, but the answers are either too broad and could mean a huge number of things in physics, or it does not even show up on Google searches.
Can someone please explain what these three terms mean, and how they are similar to one another, how they differ from one another, and why are they usually being talked about in the same breath ?
