Non-uniform is space? Not directly no. A series of HTC can be defined via a number of cutout objects that externally abut the solution domain. These can be defined manually or be created automatically from another model when you use the 'Zoom-in' functionality.

I tried the first option and it work generally fine, except for the postprocessing whereby the cutouts had temperatures of the ambient/global. When I posted the question, I was thinking more of writing a general function of HTC=f(x,y) at the low z. But since the first option solved the problem, I shall lived with it. Thxs for your help Robin.
