A uniform grid is deformed to a grid clustered around an arc of a circle. The radius of the circle then increases as time increases and the grid is adapted to the expanding circular arc. The circle is initially located with its center at (0,0) and radius 0.5 the final radius is 1.0.

A 60 x 60 grid was used on the unit square [0,1] x [0,1]. The time step dt = 0.025. The final time was t = 5.5.
