the "divide surface" button is only needed if TRNBuild calculates
that the specific mass flow rate (kg/h.m2) of the floor you are
proposing is below the allowable limit. If the specific flow rate is
below 13 kg/h/m2 then you have to segment the floor into multiple
floors in series (and the "divide surface" button will become
active.<br>

TRNSYS calculate the minimum allowed inlet mass flowrate in

I am not sure about these but have forwarded the question on to our
Transsolar colleagues. I will let you know as soon as I hear back
from them.<br>
