How do I plot a flow field as stream lines on a 2-d plane?

You can plot streamlines based on a velocity that has no component normal to the plane. For example, if you are plotting on an x-y plane, the velocity in the z direction would be 0.0 m/s. To set-up this particular case (x-y plane) in CFX-Post you would: 1. Create expressions for the velocities in the 3 directions, e.g. Uvel = Water.Velocity in Stn Frame u Vvel = Water.Velocity in Stn Frame v Wvel = 0.0 [m s^-1] 2. Create a new vector variable with "X Expression" = Uvel "Y Expression" = Vvel "Z Expression" = Wvel 3. Create a line within the plane on which you wish to plot. A sample line will give more even spacing 4. Create a streamline starting from the line created in 3. and using the variable created in 2. Using "Forward and Backward" may by most satisfactory. |
