John,
Thanks for the suggestion, I'll have to look into it.
I was also given the suggestion of mapping my BC's
to one of the nodal co-ordinates [c/o Chris Wright]
after making suitable selection of surface nodes.
That was the part of the loading I was seeking; i.e.
ANSYS automatically making the pressure distribution
variation along an area then applying to nodes.
I had not used the component feature for making specific
loading distributions. Previously I have only used the
components mostly for sub-set selections.
