Hi everyone,
I am doing a transient simulation in Fluent and I am trying to export temperature and cell volume data of a specific domain to post process it in Matlab. I defined it with a cell zone but I can't export the entire cells in volume. There are 2 ways.
If I select nothing while exporting, Fluent gives me all the cells in my simulation and this is a problem for me because I can't use it. If i select only the cell zone I want, what I obtain are the cells value only in surface (I think), but i want it in all the volume. (The total number is 360'000 and i can see just 33'600 cells.)
I did many attempts but no results. I also tried to delete other cell zones but Fluent don't allow me to do It and it crashes. (I think because I set shell conduction)
I hope you can help me,
Thanks in advance
Luca

File=>Export=>Solution Data and just choose the cell zone but don't select any surfaces.


There are also more faces than cells, so if you think you see fewer face values than cell values, that's also just plain wrong.

Hi,
thanks for your reply but let me explain better.
As you can see in the photo i attached, if I want to export file in ascii format, Fluent doesn't allow me to select directly the cell zone (I can t understand why). So I have to select the zone i want in the other section but this doesn t work.

Definitely do not select anything in the middle surface column, doing so will indeed not export volume data and give you surface data. Older versions of Fluent there wasn't even a selection for cell zones & you could only dump all the cell zones. Maybe it's not doable for you this way.

A workaround is to write an interpolate file. File=> Interpolate. Here you can select individual cell zones and individual variables to export. And this works in just about all versions.
