I am modeling an internal fan in an enclosure and I have the following questions:

1. The fan I am modeling does not have a fan curve because it is an HVLS fan. When defining the fan, do I choose axial, fan curve or raidal? I know the maximum CFM of the fan but I don't know what to put in the table.

2. Should I impose boundary conditions on the fan? If so, how should I do that? The face used by the boundary condition can't seem to be the same face used by the internal fan.
