We have got a school which is operational from 6 AM-2 PM here in India. The school would be cooled in the night through the usage of free cooling wherein they would be providing the exhaust fans and exhausting the air inside  and due to pressure difference air from outside will come inside and there by night temperature will be maintained in it.

Normally while doing the thermal analysis Trace 700 would do a 24 hour simulation , however in this case we would require to do the simulation only during the operational hours ( 6 AM-2 PM). So can you please let me know how to do the same  in  TRACE700.
