LaMaGa: Deterministic flow pattern (I)

Subject: Fluid mechanics.

Explanation: A circumference of unit radius centred on (2,0) is advected by a deterministic flow field given by a clockwise vortex of unit strength plus a sinusoidal flow pattern xt=sin(4y), yt=1/2 sin(4x), until t=10. The number of points on the curve is adaptative.

Bibliography: See these slides of a talk by S.N. Santalla and J. Rodríguez-Laguna in the UAM in 2003 for a short explanation.
