Robert Caulk proposed the following answer:
Hello,

bndCondValue [1] will prescribe pressure if the boundary condition is
indicated as pressure [2]. Otherwise, the flux will be zero.

>What is the difference between [0,1000,0,0,0,0] and
[0,-1000,0,0,0,0]????

Since these values are the imposed pressure, 1000 would be imposed as a
positive pressure value, and -1000 would be imposed as a negative
pressure value.

Cheers,

Robert
