I spoke to our ICFD team.
"There is a new keyword available in versions Dev/R13, called ICFD_INITIAL_TEMPNODE which allows the user to give an initial temperature for each internal node ID of the ICFD surface mesh. So he may be using that but it may involve some codding and file manipulation on his behalf which, I agree, could be cumbersome. The keyword ICFD_INITIAL also allows the user to use *DEFINE_FUNCTION to define a temperature but again, not great for what he wants to do."
To be continued.
