Measured Temprature Profile

Hi all,

I am trying to use measured temperature profile as boundary condition. I've seen in some tutorials that there is a possibility to use "Option", then "Function", "Interpolation",,,etc. Perhaps this was possible in the older versions of COMSOL but in 4.3 it is not possible to find Function under the Option menu. Is there a quick way that explains how to use measure temp profile as a Boundary Condition.

Kind regards and I appreciate every help.
