Dear Rawad Jamil Deeb

I had the same problem. I suggest you to write the results in a file (as an option in Fluent) and show your results in another software such as Tecplot and Excel.

Dear Mojtaba Bezaatpour ,

Thanks for your answer .. I have already done this .. But I still do not know any value for variable 1 at any particular point on the surface of the pipe (for example what is the value on the surface of the second pipe at the same starting point of the first tube "within the Excel file").

Rawad Jamil Deeb : But you could organize the output to contain (x,y,z) coordinates of points on the surface together with curve length and variable parameters. If that is not possible from Fluent, than just export the results data to CFD-Post, create a Polyline by intersecting the pipe with a perpendicularly oriented plane and export the required data on this polyline curve as CSV from CFD-Post. Any set of solution variables (e.g. from a CDAT file) can be exported, including point coordinates (x,y,z) on the polyline. If this information is available in e.g. an Excel spreadsheet, you could easily sort the data to have the same identical circumferential starting point.

Regards,

Dr. Th. Frank.

It can be easily distinguished by simultaneous comparison between excel results and contours of both tubes. For example, you can draw Nu contour on both tubes and see which of the pipes has a larger Nusselt value at a particular point. This comparison helps you know which value corresponds to the pipe at the same point.
