Residuals are stable and don’t converge

      Hi,


      I am a beginner in ansys fluent, i am trying to simulate the air movement inside a closed tunnel greenhouse (no inlet and no outlet), the boundary conditions used are: Greenhouse cover temperature T= 300k, Greenhouse floor temperature T=308k. When i start calculation, the residuals stay stable and don't converge.


      please see these screnshoots for all my work steps and tell me where might the problem is ?

      Put some monitor points into the system, temperature and velocity specifically.  As it's natural convection it may well be transient, the monitors will tell you how much this affects the results.
