Certainly I have read it . but in the documentation i have found that the method is coupled.i want to know that :is this the method for all types of problems?i mean in fluent the method can be chosen easily coupled or staggered.what about cfx???

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.
