Hi everybody Dear! I want to see the contours of STREAM FUNCTIONS.

The problem is that my problem is 3D so I donot

get any option for Stream function under Velocity

Cant it happen that I make a plane and observe Stream

Function contours on it? Please help me or if you have any suggestions?

The Stream Function is not defined in 3D since it is only a 2D flow representation.

Ok sir, I know that all. and I got your answer but cant I see Stream Functions on a plane. I am still annoyed because I saw a paper in which a 3D problem was done and stream functions were observed! Thanks

you can plot the "pathlines" for your 3D case... serves the same purpose for flow visualization.

Dear Sir
My name is Hussam Ali Khalaf, postgraduate student in Iraq and Am currently working on “A Solution Algorithm for Transient Fluid Flow with Multiple Free Boundaries”
I have results for velocities values (u and v) in directions x and y for undular bore evolution (please, note the file attachment), rectangular uniform mesh (2Dimension, (i,j)=(22,10)) consists of 20 cells in the horizontal direction (length=12 , ∆x=0.6) and 8 cells in the vertical direction (height=1.6, ∆y=0.2).
Am supposed to draw velocity vector, streamline and stream function. I have a program TecPLOT, I have tried several times but I don’t fully understand how TecPLOT reads the results, would you please help me if you have any idea on how to go about it.
Thank in advance

Yours sincerely
