Potential Flow Streamlines

Streamlines can be define by a streamfunction expression in cartesion coordinates.
Coordinates can be entered as follows: 

      x -- x ordinate, y -- y ordinate
           Operators : * / + - ^
           Functions : sin,cos,ln,atan,sqrt
Note : there is no guarantee that any chosen function is a valid potential flow. You need to verify all functions using the continuity equation.

Streamfunction Expression :


atan(y/(x-100))-atan(y/(x+100))
