Need Help for define-adjust

Hi
Could some one please let me know how to write a UDF to assign a volume averaged temperature in a domain.
i know i should use define_adjust but i didn't find an appropriate sample in udf's manual.
in fact the problem is that there is a tank full of water, with no lid and in contact with air. so a fraction of water volume which is in the top of the tank has the same temperature as air. i want to put it as a BC. another thing is that the air tempurature isn't constant.
thanks in advance

You can fix temperature of a block of domain in cell conditions without UDF writing.
