Thank you for the help with commands, it happears as if the film coefficient and bulk temperatures are not interpolated (note that I have used the APDL commands I sent in the reply before, but started the X vector from 0.13 instead of 0):

Reading results into the database (SET command) will update the current
displacement and force boundary conditions in the database with the
values from the results file for that load set. Note that any
subsequent solutions will use these values unless action is taken to
either SAVE the current values or not overwrite them (/EXIT,NOSAVE).

USE LAST SUBSTEP ON RESULT FILE FOR LOAD CASE 0

The surface loads listed are the current database values and are not
necessarily the values corresponding to the current results data set.
Tabular boundary conditions, however, do list values corresponding to
the current results set.
