solution method???
 
hi:
can any one help me with my problems in cfx numerical solution method(discretization)?
*coupled or staggered???
*upwind(first or second order),QUICK or...???

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.

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???
thanks for your help

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.
