Default Convergence Problems

Hi, I am simulating the airflow within and around a greenhouse structure. I am not using BFC's so to model the roof geometry correctly I need alot of cells inside roof structure itself (for parsol), and this increases the grid density in one region of the x and y plane of the domain quite dramatically. The result is slow convergence of higher order schemes (eg mimmod), 8-12 hrs for 2D simulation with relaxation 2 orders tighter than hybrid. Hybrid converges ok after a 1-2 hours. Any help atall would be really appreciated
