A hard one: how to get spanwise average in Fluent?
The computation domain is constructed by simply repeating structured 2D mesh in z-direction (spanwise), and I want to get the spanwise-averaged field variables. I tried but still could not find the way. I have thought of several methods as following:
1. Use UDF. The UDF will need to get the neighboring cell in z-direction. I don't know how. 2. Export data file from Fluent and do the average in Matlab. But the exported file is in PEBLOCK format, and there is a lot of connectivity information in the file, and I also don't quite understand the organization of data in that file. 3. Read the exported file or read Fluent case and data files directly into Tecplot and do the average. I checked and could not find the way to get spanwise average in Tecplot. 4. After reading files into Tecplot as in 3, export a file with better format (like IJK-ordered) from Tecplot, but I can only export files in FEPOINT or PEBLOCK format. Anybody any suggestion? Thanks! |
Hello Ivanbuz
I have been suffering about same problem. Do you have a solution so far? thank you |
Hi,
I've done it by using tecplot as an interface media, here's the instruction: - first by a journal file export number of planes data in span direction for tecplot. - write data exported in tecplot as new files. - export new files to matlab and compute the average. |
