Fluent pre-processing
 

Hi all fluent users,

I have kind of general question...
How to check that the model mesh, parameters and initialization are good and accurate before running the calculation in fluent?
I am asking this because when I started the iterations for my model, it seems that it is not gong to converge, and I don't know exactly what can be modified to fix this problem?

My case includes:
Turbulent k-epsilon- Enhanced wall functions
VOF - open channel

Boundary conditions: Mass inlet and pressure outlet

The other controls and parameters are set as default.

Thanks for any advice.
