HELP!boundary condition in SIMPLE
hi,I am now using versteeg's An intro to computational fluid dynamics as my guide and I have several questions on boundary condition,if I was wrong plz tell me!

1.In AppendixC,it mentioned that in the momentum equation,there is a source term Su.But in Patankar's book it was not mentioned.Is this term necessary?
2.In the pressure correction equation,should I calculate all the scalar nodes?I mean,if u also have the versteeg's book plz refer to the fig.9.12,should I calculate the pressure correction for J=2?

Thank you for your kind help!
