Hallo everybody,

I am simulating a 3D natural convection problem in an inclined enclosure with large aspect ratio.Tthe case consist in two isothermal plate (lower hot, upper cold ) and adiabatic side walls.

Unfortunately, this simulation is giving me a lot of problems, especially with regard to convergence and with the results, in particular in the reading of the average nusselt number.

I have tried to understand the errors in the simulation but due to my inexperience in the field of simulations, I have not been able to give myself an answer.

I have prepared a summary document with some questions so as to be more specific and give the necessary information to understand the problem.

The summary can be downloaded here: https://we.tl/t-6tSiOKE6Y9

Thanks in advance
