11/15/2010 Math Modeling II, Fall 2010 (Dr. Xin Li) 1 Level Sets Numerical Considerations Lagrangian Formulation Consider the curve given by ø(x,y)=0. c r Suppose that the velocity is known for every point on the curve. To move the points on the curve with this velocity, we need to solve ) ( V c d r r ) , ( y x V r For every point (x,y) on the curve. , y x dt =
