Default OpenFOAM - BC contribution to source vector

Hi all!

If I am not mistaken, the functions .diag(), .lower(), .upper() and .source() return the respective coefficients from the matrix of coefficients, right?

All of them do not account for BC contributions. I know this was already discussed a couple times in this forum, but I was not able to find out how to get the matrix and source vector with the contribution of BC.

I am using a simple 2D heat transfer problem (steady state and no sources) to compare coefficients. For me, it seems that functions .D() or .DD() return the matrix with BC contirbutions (I am pretty sure they do different things that I can't see wiht my simple example), but I can't find out a simple way to do that with the source vector.

In other words, if my system is [A]{T} = {B}, how can I access [A] and {B} with BC contributions?

Can anybody help?
