Description: Computer simulations of gas-liquid flows require the tracking of a deformable interface moving through an array of stationary control volumes. Here, a spherical bubble is tracked as a collection of discrete interfaces residing within unit-cells. The gas void fraction corresponding to each unit-cell is displayed in colour, resulting in a pattern. This pattern changes as the bubble is moved and stretched.
