Circulation fans


Hi all, would like to check, using the HVAC example as a base model, if I were to add in a fan (e.g. a jet fan) for circulation, how should I go about setting the boundary conditions?

The only suitable option available in butterfly seems to be the “inlet boundary”, but I suppose it’s not exactly an inlet since this fan doesn’t change the total air volume…?


@cyshimz Butterfly is not supported the fan!!! If you intend to do this, maybe you need use OpenFOAM.


@minggangyin I am very new to butterfly. Is it possible to write a python script to define it as boundary condition?
