About node based calculation

Hi everybody, just a question ! Has anybody ever tested the node based gradient calculation especially for multiphase flow ?

Thanx for answering !

It usually gives better results. But it uses slightly more memeroy and often grid interfaces fails.

ok, but is the scheme conservative towards the variables ? it seems, for instance, that the 2nd order discretization scheme is not suitable for multiphase flow. That's why i ask about the based node calculation
