Computational Capabilities
Overview
The FAST research group has computational capabilities that span from 0-D scripting for design space & performance mapping to high-fidelity 3-D computational fluid dynamics (CFD) needed to investigate localized phenomena. For design-space & performance mapping, we use the open-source tools of Python with NumPy, SciPy, MatPlotLib, and others for single channel solvers and heat exchanger design tools. For high-fidelity CFD modeling, we use the DoE Nuclear Energy Advanced Modeling and Simulation (NEAMS) open-source code, Nek5000 and the open-source code, OpenFOAM.
The FAST research group leverages the computational capabilities of the Virginia Commonwealth University's High Performance Research Computing Core teal cluster. The teal cluster consists of ~4500 cores of mixed AMD and Intel CPUs with 2-4 GB of ram per core.
