Hi guys..!

I'm a beginner with CFD (and FLUENT) and I've just encountered one of my many problems to come. I've modelled a cube (a volume, in GAMBIT) as a room for which I intend to analyze the airflow within it. Next, I drew to squares to represent the inlet and outlet of the air conditioning system. I've meshed everthing and defined the boundary conditions as VELOCITY_INLET for the a/c inlet and PRESSURE_OUTLET for the outlet. Also, for the walls, I've modelled all of them as WALL. As for the continuum, well it's fluid.

My problem now is that once I've read the .msh file to FLUENT, it seems that FLUENT doesn't recognize the VELOCITY_INLET and PRESSURE_OUTLET I've specified in GAMBIT. The only boundary conditions that I can set are or the walls I've created.

I've tried uniting using Boolean of the inlet and outlet of my model to the 'room' (volume) in Gambit without success.

Can anybody help me? Thanks..

YOU FIRST SPLIT THOSE SQUARES WITH WALLS AND MESH AND GIVE BOUNDARY TYPES AS VELOCITY INLET OR PRESSURE OUTLET OR ANYTHING

You make all boundary's as wall's in GAMBIT, and then in FLUENT make boundary's you'd like
