As far as transition is concerned, the Z-Method appears to perform far better than the standard monozone H-NS approach. The CPU savings allowed by the Z-Method are close to 20% against the far less precise H-NS solution. In assessing this performance, one has to keep in mind that it is quite impossible to reach the same level of accuracy with the standard H-NS approach without a dramatic increase in cost and rising of hardly controlled numerical instabilities.
