ABSTRACT:
Over the last decade hydrodynamical simulations of galaxy formation advanced significantly. I will present recent results using a new hydro scheme based on a hybrid approach combining classical Lagrangian and Eulerian methods. Specifically, I will focus on differences between these classical schemes and the new hydro method demonstrating that the global gas structure, the global star formation history, properties of galaxies and the IGM gas supply to galaxies are
significantly changed compared to previous calculations. Most dramatically, galaxy gas accretion is altered leading to a significant increase of hot mode accretion compared to previous predictions.
