I have seen this happen before as well; where the inlet mass flow rate is
above the required minimum but yet you still get an error saying that the flow
is too low. I worked with Transsolar on tracking down the cause of the problem
and we were never able to. I try to keep the inlet mass flow rate at least 10
to 20% higher than the minimum flow rate. Adrien's response is a good one; use
the autosegment feature to break your floor up into two or more floor segments
in series and your minimum specific flow rate will drop far enough below the
5.4 kg/h.m2 that you are sending it.<br>
Kind regards,<br>
