Large Eddy Simulation (LES) of Sandia's 1m helium plume test case with OpenFOAM . The video shows the helium mass fraction (left) and the velocity magnitude (right). The base mesh is comprised of 6 cm cells with a cylinder (2 m in diameter) refining the grid size to 3 cm and another cylinder (1.5 m in diameter) refining the grid size to 1.5 cm. This change in grid size can be seen at the local velocity magnitude at heights of approximately y =1.5 m - 2 m.
