How to define moving-nonuniform film coefficient and reference sink temperature for convection?

Hi, 

I would like to define the moving non-uniform film coefficient and reference sink temperature based on nozzle location for the thermomechanical simulation of additive manufacturing.

I use event series and ABQ_AM_... table collection to define element activation and laser-induced heating. We can use the FILM subroutine to define the non-uniform film coefficient and reference sink temperature. How can we integrate nozzle location (Event series) to the FILM subroutine in each increment so that I can update the parameters based on the relative distance of elements to nozzle location? 

Do you recommend any other way to define the moving-nonuniform film coefficient and reference sink temperature for convection?

Thank you.
