The purpose of this JAVA applet is to display a vector field which the user can input by typing the equations for the x and y Cartesian components of the vector field. Click here to call this applet. The application can also perform a series of tasks with the vector field inputed by the user. The tasks are:
- Draw streamlines of the vector field that pass through a point given by the user by mouse clicking the display area.
- Draw path lines of the vector field that pass through a point given by the user by mouse clicking the display area.
- Draw streak lines of the vector field that pass through a point given by the user by mouse clicking the display area.
- The user can input a material contour by mouse clicking the display area. The application can evaluate the circulation on this contour if the appropriate button is clicked. The application can also compute the new position of the material contour at a given instant of time inputed by the user, and circulation of the contour at its new position and shape can also be evaluated.
