What steps will reproduce the problem?

CFAST version : 6.1.1.54
Action : 1) addition of new material to thermal.csv

Cannot reproduce this problem as it relates to the thermal.csv file.  CEdit 
does show an error in the 
specification of the mechanical ventilation system that seems to be an error in 
the GUI.  At the moment for 
the floor, the minimum distance to the specified height of a mechanical vent is 
the (square root of the vent 
area)/2 (this just assumes the vent is a square centered at the specified 
height).  For the ceiling, the 
calculation does is not divided by 2 as it should so you get the error with 
this test case where the vent height 
is 3.6 m, vent area is 0.24 m and ceiling height is 4 m so that the error check 
is 3.6 + sqrt(0.24) = 4.09 m 
which is greater than the ceiling height.  This has been fixed for the next 
release of the model.

As a workaround, just adjust the vent area or height so that the error check 
goes away.  There shouldn't be a 
big impact on the overall calculation.

Fixed in revision #200
