Hello guys.
I'd like to calculate the Wake length behind a circular cylinder for Reynolds number 40 (2D Geometry,laminar, steady) in Star ccm +. My Drag coefficient is 1.1864 . How can i calculate the Wake length in Star ccm? I know,the Length of the Wake is, Lw is defined as the streamwise distance between the confluence point (wake stagnation point) and the rear stagnation point of the cylinder.

Won't plotting u_x on the center-line behind the cylinder and looking for a sign change work?
