A uniform grid is deformed to a grid clustered around a pair of circles. The grid then moves with the circles as their centers move to each other and the radii are increasing.

A 50 x 50 grid was used on the unit square [0,1] x [0,1]. The time step dt = 0.025 and the final time was t = 5.5, increments of 20 time steps were taken for the animation.
