Cooling effect of water flowing on the rooftop

I am doing a simulation on flowing water on the rooftop of a model which is 15cm (H)x 30cm (L)x 52cm (W), to monitor the heat transfer of the roof and also the temperature distribution in the model.
I try to built my simple model using gambit by creating a 2D rectangular box with another face of 1cm height as my flowing water:
________________ --> water surface
________________ --> water outflow
|.....(inner air)...... |
|.........................| --> rectangular box with a small opening for ventilation (pressure outlet)
(I set my roof plate as a wall boundary which is hot plate, producing heat to the inner air.)
After that, i try to import my mesh into Fluent (in Ms Window), but the warning come out as follow:
Warning: Both outflow and pressure boundaries are present in the
domain. This is an incompatibility and solution cannot
proceed until this is fixed.
So, what should i set for the next in order to fix the warning above.
1. Since i have two phase, which multiphase should i use, VOF? (but it cannot simulate the heat transfer problem)
2. Is it one of the open channel problem?
Hope someone can help me... Thanks in advance
