Visualizing the dynamics of two-dimensional foams with FoamVis

► A novel interactive computer program FoamVis provides techniques for visualization of foam simulation data. ► It is used to describe correlations between different attributes in flowing foams. ► We show that topological changes correlate with high bubble velocities in flow through a constriction. ► We show the forces acting on an ellipse sedimenting through a foam. ► We illustrate the changes in bubble size during diffusive coarsening of a foam containing two gases.
