Natural ventialtion for buildngs!!

Elleana

Hi,

Wondering if anyone who has past experience in dealing with natural ventilation problems could please help me out.

I have the model and mesh ready for the building.

I am modeling the internal conditions when the louvers are actually shut.

I would like to see the temperature stratification in the space. i have applied the heat sources( people and lights) in the space.

I am using a P1 radiation model with a laminar flow.

I have problems with the convergence and don't seem to be getting the temperature contours right either.

It will be great if someone could please throw their past experience on this.

Thanks

Kind Regards

Elleana
