style='font-size:10.0pt;font-family:Arial;color:navy'>Since an active floor wil
generate heat flows up and down, which usually are not identical (due to the
position of the active layer in the floor, but also due to floor covering and
different convective heat transfer coefficients), you usually need to model a dummy
zone and simulate both heat flows. Could this be a solution to your
problem?<o:p></o:p></span></font></p>
