If we prescribed velocity at boundary we don't need special treatment for pressure-correction equation (dp'/dn=0) but I had problem when I define pressure constant boundary condition (p=constant, p'=0) , I need special treatment for central coefficient of p' equation at boundary nodes?

on the wall, dp/dn is not zero at all. it's something like
suppose on the right wall dp/dn = 1/Re d^2 u/d x^2 when Re is high, the R.H.S. reduces to zero. |
