Hi again,

Hope that the question I am asking could help a lot of users too. I am thankfull with the help that could come.

I have modeled a kind of house to simulate the heat transfer from a heat source that will  arrive to the house in pipes. In the pipes there should be an internal fan, but.. instead of that I would like to know if it is possible to force and inlet of a volume rate instead of defining a fan curve. In a simple way:

- Image a straight tube using external flow.

In the midle of this tube is possible to impose a fixed volume flow rate ? My desire is to see the chart of the effect when inflanting and dischaging freely.

(I want to see the air going from one side of the tube to the other without any lid stoping the fluid to go.)

Best Regards,

Nuno
