Mixed Eulerian Lagrangian method
 

Hi all, I am solving for free surface profile in a 2D flow by using mixed eulerian lagrangian method (Longuet higgins and cokelet, 1976). When I increase the number of panels on free surface too much, I am getting singularity. Anyone can tell me why it is happening or the possible bug in my program I should check for ?? posted by: Shantanu
