I am doing a transient heat transfer analysis for a 3d geometry and want to write temperature data for every time step from various surfaces.
I had around 25-30 surfaces for which I need to write the data separately for each one. When I select all the surfaces, fluent is finding average value of all the surfaces and storing one value ( which is averaged value).

How to save data for all surfaces separately without getting averaged.

Regards.

Create a monitor for each surface, that'll give you options to plot/export that surface average (or max, min etc) as a unique file per surface. Sounds like you've gone through the process but averaged all the surfaces.

Thanks for your help and I too read about this method. But I have exactly 40 surfaces for which I have to write data for temperature, total surface heat flux, nusselt number. Along with these I have to write temperature data for 40 more points.

Writing these many report monitor files is taking huge time and that's why I am looking for other alternative.
Will it be possible to write data without averaging the values, even though we select more than one surface for a single monitor file.

Thanks.

You'll need a monitor for each point and surface, but you should be able to save many monitors to a single file. However, if you want that much data you'll have to pay the cpu/time costs associated with it. Have a look to see if you can take data every some time steps: chances are you don't need all the data.
