I believe that the LBPM Domain object will remove layers at the inlet if an external boundary condition is applied. See line 1407 from common/Domain.cpp
https://github.com/OPM/LBPM/blob/master/common/Domain.cpp
This should also be visible in the output data. The reason this is done is that the presence of solid can influence the value of the pressure and/or flux that would need to be set (since the interfacial forces would also need to be accounted for).
It is possible that a pressure / flux BC will "work" without removing these layers, but I expect that it would reduce the range of stability for the core flooding protocol.
There are internal data structures that store the pore sites along a face, since these are used in the communication structures. These correspond to the values that need to be sent / recieved by the MPI communications, and could be used within this context if necessary.

Thank you for your attention, Professor James McClure,
Regarding our discussion about the inlet position of "Pressure (Nx * Ny + Nx + 1)", I would like to emphasize the importance of correcting line 419. It is crucial to accurately account for the relative permeability in this correction.
419 double pressure_drop = (Pressure(Nx * Ny + Nx + 1) - 1.0) / 3.0;
In the equation above "/3.0" is outside of the parenthesis dividing the "Pressure(Nx * Ny + Nx + 1)". The correct form should be represented by:
419 double pressure_drop = (Pressure(Nx * Ny + Nx + 1) - 1.0/ 3.0);
Also, if possible, please take a look at the other issue I submitted (#85). You might have missed it
