First off,
I am quite a newbie in this cfx world, so pardon me if the question is dull, but I searched for the problem online and could not find any answers, actually it kinda looks like a bug to me.

I made a plane colormapping the temperature and received quite strange values. From the colobar one would guess that all the values of temperature lies between 302 to 303 K, but in the calculator I get that the min value is 310 K and the average is 351 K, which seems more correct for my case. But I would like to display my results in pretty colors.

I attached a screen of the problem.

I don't think it makes difference, but I am trying to simulate a compact plate-type simple heat exchange with two different fluids and 60 isolated regions.

I do not understand your question.

But make sure you are aware of the difference between conservative and hybrid variables, such as this FAQ: https://www.cfd-online.com/Wiki/Ansy...t_the_walls.3F

Thank you very much. I was unaware of the effect of hybrid variables in the temperature and it was set to hybrid by default and I did not realize it.
I switched it to conservative and now I am getting the expected values.
