Hello dear community,

I am simulating a flow in a greenhouse using the buoyantBoussinesqSimpleFoam solver, but I am having difficulty obtaining convergence in my calculation. I have tried modifying the relaxation factor, but it has not solved the problem. Do you have any ideas about the possible reasons for this non-convergence?

My chechMesh:
cells: 2052391

Overall domain bounding box (0 0 0) (43.2 24 7.78)
Mesh has 3 geometric (non-empty/wedge) directions (1 1 1)
Mesh has 3 solution (non-empty) directions (1 1 1)
Boundary openness (6.00783e-17 -8.875e-17 1.15207e-15) OK.
Max cell openness = 2.51711e-16 OK.
Max aspect ratio = 88.6619 OK.
Minimum face area = 0.00488668. Maximum face area = 0.727784. Face area magnitudes OK.
Min volume = 7.44617e-05. Max volume = 0.183863. Total volume = 7343.01. Cell volumes OK.
Mesh non-orthogonality Max: 69.6223 average: 18.1421
Non-orthogonality check OK.
Face pyramids OK.
Max skewness = 0.897208 OK.
Coupled point location match (average 0) OK.
