evaporative cooling pads into windcathcer

[macpavee]

i understand that IES now has the capability to simulate evaporative cooling. -great

now, can i stick a pad into the downdraft windcatcher?

no fans, no ducts, no messing,
i am going to guess it's not that simple but any pointers will be appreciated

but a look at the daunting user guide failed to inform me as to where i can find the pads anyway.

any clues?
