Computational Fluid Dynamics, which is combinations of computational mathematics, fluid dynamics, programming and high performance computing (HPC), has grown from a mathematical curiosity to become essential tools in almost every branch of fluid dynamics. The research of CFD Lab is focused on development of efficient numerical tools for calculation, analysis, optimization and prediction of fluid flows and transport processes in environmental and hydraulic engineering at different length scales covering the whole range of hydrologic cycle from surface water to groundwater. This research topic is interdisciplinary, which will attract the scientists from different disciplines (Mathematics, physics, biology, environment, oceanography, water resources, etc.) and will offer opportunities to collaborate between Departments and Research Centers within Seoul National University, as well as with other universities, research institutions and industry. The Lab also provides an environment in which the teaching and research can proceed as effectively as possible, and it will exploit the capabilities of the HPC in furthering the frontiers of mathematical modeling.

In order to carry out large-scale simulations, we definitely have a High Performance Computer System (HPC), and most of codes have been paralleled. Following is a HPC configuration setting up at our CFD laboratory:
