CFD internal - Convergence Difficulties

Postby stefano.fusini » Sat Oct 10, 2015 9:36 am

Hi! I have a problem with the cfd internal analysis.
I have a residential house with 2 levels, and i connect them with an hole (this hole represents the internal stairs).

If I choose a single level as the analysis domain, it converges; but if I choose the whole building as domain, the analysis always doesn't converge.

I try to change the step grid, the turbolence model and the Discretisation scheme, but Mass never converges.

Please, can you help me?

Thank you,
