Hello again
I apologize for asking so many questions so quickly but on this one I am 
clueless.

I try to understand how to define complex boundary conditions  on a 3p3cni 
problem.

My question:
How to define on one boundary a Dirichlet pressure conditions and a zero value 
Neumann condition on temperature, W and N saturations?
 
This is a well posed set of condition to the best of my knowledge corresponding 
to an experimental reality where the pressure on an outlet is controlled.

Looking at the test  3p3cni columnxylolproblem.hh, I note that, as expected, a 
pressure dirichlet conditions can be applied but "setALlDirichlet" hides how 
this pressure condition is used in the system.

 The 4 equations being energy + 3 mass conservations it is unclear to me how 
such pressure condition is used.

I tried to go through the source to find it but no luck so far..[ I am not an 
expert c++ programmer]

which bring me to reformulate my question: 
How do I define a set of  BC with Dirichlet on pressure and Neumann on 
everything else in the context of a 3p3cni model?

I tried a "trick" :
 Assigning all boundary condition to DIrichlet and then changing Temperature, w 
and N saturation condition to Neumann but it does not seem to work... 


Thanks a lot
JF
