for ploting the iso surfaces parallel to x axis i use following scheme command

(Do ((x -0.004 (+ x 0.0005))) ((> x 0.027))
(Ti-menu-load-string (format #f "surface iso-surface x-coordinate x=~a , , ~a ," x x))
)

for y axis i just change the x in x-coordinates with y

i got successfull in ploting line surfaces in vertical directions i.e. parallel to y-axis by using following command

(Do ((x -0.004 (+ x 0.0005))) ((> x 0.0271))
(Ti-menu-load-string (format #f "su line-surface x=~a ~a -0.0015 ~a 0.0015" x x x))
)

but i want to plot LINE-SURFACES not iso-surfaces parallel to x-axis i.e. horizantal
but i m unsuccessful

if someone guide me then it will be very helpful
Thanx in advance

Never mind get successful

actually i m calculating bulk temperature in a 2D domain thats why i am using these surfaces

my procedure is simple plot these lines write ascii files with the information of velocity and temperature then by using the matlab i am calculating the bulk temperature to calculate Nusselt number.

if anyone want to recommend any thing regarding this procedure than always welcome

Impressive. Every successful use of scheme is impressive.


But I don't know if it is efficient use of your time; depending on how you define bulk temperature, you might not need Matlab at all and can do everything in Fluent.

i have digged deep this forum regarding discussion of bulk temperature as stated by LuckyTran working out for bulk temperature by doing this method its a very bad guess.


but the recommended method is to develop custom field function for every surrface i.e. integral/sum of temperature * velocity and divide it by intergral/sum velocity but creating it for every surface is kind of donkey work but here scheme command comes for help to automatically make monitors for every surface. for wall temperature make the vertex average of points.



(Ti-menu-load-string (format #f "s m su set tu~a ~s tu x=~a () no no yes tu~a 1 yes flow-time" x "Integral" x x))
(Ti-menu-load-string (format #f "s m su set u~a ~s velocity-magnitude x=~a () no no yes u~a 1 yes flow-time" x "Integral" x x))
(Ti-menu-load-string (format #f "s m su set tw~a ~s temperature point-~a () no no yes tw~a 1 yes flow-time" x "Vertex Average" x x))



but for averaging over time i still have to use matlab to sum the information over time. i know we can use data sampling for time averaging but i havent fully explored this idea. i hope when u say it can be done all by fluent u mean all of the above procedure or am i missing something

Yes, I mean all of the above. It might all be possible in Fluent without Matlab or Scheme, but that completely depends on how you define bulk temperature. I have no idea what is your definition.
