Argonne National Laboratory's computer visualizations of arterial blood flow and the dynamics of early galaxy formation both recently won Office of Advanced Scientific Computing Research awards at this year's Scientific Discovery through Advanced Computing program conference.
"We are fortunate to have the expertise in software development and computation as well as the hardware resources necessary to make these visualizations possible," says Argonne's Joseph Insley.
The blood flow visualization shows detailed models of blood flow that can help researchers studying the interactions occurring between physical phenomena happening at different scales. The galaxy formation visualization models the gravity and gas dynamics of early galaxies and their interaction with light to help researchers understand the impact heated gas had on star formation.
"These visualizations not only help scientists understand massive datasets and accelerate discoveries but also serve as great examples of how collaborative teams and pooled computational resources can help advance large, complex problems," says Argonne's Michael Papka.
Both simulations were computed using resources at the U.S. National Institute for Computational Sciences.
