So what are you asking?

The discretisation is discussed in the documentation. Have a read of it for a description of what is available and how it works.

In CFX it does not require pressure-velocity coupling as the fully coupled solver incorporates the coupling in the linear solution. CFX does not have segregated P-V coupling options like SIMPLE, SIMPLEC if that is what you are asking.

The CFX solver is similar to the Fluent V12 solver when in coupled P-V coupling mode.
