Heat transfer coefficient is defined as q/delta_t

q = heat flux ( w/m2) and delta_t = temperature difference.

If you know these two you could find your heat transfer coefficient.

Dear Arky

I am also facing the same problem. I want to specify heat transfer coefficient at various points in my domaain. But that option is not directly available in "Read profile" option. Can you please tell me how I can specify the heat transfer coefficient through udf/some other way?

Thanks in advance

Ravi
