All,

I have a general question about coupled solvers for NS equations: does it simply put the segregated coefficients for X-momentum Y-momentum and continuity into a giant matrix and solve, or does it fully linearize all the terms?

i.e. in the matrix, do the X-momentum equations include implicit y-velocity components in the matrix, and vice versa?

I hope my question is clear.

TIA

EDIT: to further clarify-- does the benefit of stability and convergence rate only come with coupled solvers when all the implicit terms are included i.e. fully-linearized, or in general, is there benefit even if the coefficients are essentially the same as the segregated solver, but the pressure and velocity are more directly coupled?
