Are residuals in Fluent just the average of all the residuals on each and every cell?
 

Hi,

I am well aware of the Gauss-Seidel, Jacobi methods for solving matrices. I was wondering if the residuals in the Fluent solver are the mean of all the residuals of each and every cell (for finite volume) or node (for finite difference)?

As I understand, every unknown value has a residual in an iteration. In that case every node/cell has a set of unknown parameters. This was my logic. Please correct me if I'm wrong.

Thanks in advance.
