The mission of Argonne's Computing, Environment and Life Sciences (CELS) directorate is to enable groundbreaking scientific and technical accomplishments in areas of critical importance in the 21st century. The goals are threefold: advancing biology, advancing the intersection of computing and biology, and advancing all activities involving computation. To this end, the CELS has integrated Argonne's research in the life sciences (systems biology, bioinformatics, computational biology) and the computing sciences (applied mathematics, computer science, and computational science) and has established a leadership computing facility essential for advanced simulation. http://www.cels.anl.gov Argonne National Laboratory Scientists use meshes to approximate a geometric domain for solving complex engineering analysis problems. To assist in these efforts, researchers at Argonne have developed the Mesh-Oriented datABase (MOAB), a software component for representing and http://www.cels.anl.gov/news/detail.php?id=907 High-fidelity simulations allow researchers to understand how injected fuel, air, and combustion products intermingle when the engine is fired up.
