fluent can't plot 3D graphs; you can extract data by exporting them and plot them in excell or in Matlab (better). A

Why is Matlab better?

It just is!

Excel is quick and dirty. I like it!

how can we extract data from fluent. Actually I want to plot axial distantce V/s Radial velocity (is dimensional less)i.e radial velocity/ (r*w), where r = radial coordinate & w = rotational velocity of refernce frame, These at different times that are also dimensinal less t/Ts t = actual flow time and Ts = sqrt(w)/sqrt(E) E = ekman number.

If your case is time dependent, save frequently (by outsave) and run a macro that save in a ascii file the variables that you need. After import them in matlab and good luck :)

If you have just performed the calculation, write a matlab cod that write a fluent journal file such as:

read-case xx-1.cas read-data xx-1.dat //file/export/ascii pathFile\nomeFile-1.YYY nomeSurfaceOrInterior () yes listOfVariables

read-case xx-2.cas read-data xx-2.dat //file/export/ascii pathFile\nomeFile-2.YYY nomeSurf () yes listOfVariables

....

read case xx-N.cas read data xx-N.dat //file/export/ascii pathFile\nomeFile-N.YYY nomeSurf () yes listOfVariables

hope it's helpful

good luck

There is a matlab code that reads all the data is acsii in one big file and you can use it to plot the data. I don't think you can do a 3D plot with 2 varaibles.

Here is where you can get it:

hi

I din't understand what u told me. i dont know how to write code in matlab. can u please explain in detail or do they have any documentaion regarding this. Thanks Ketan
