I'm trying to coding Immersed Boundary method, but there are several questions need your help

1, If I simulate a 2D square whose boundary is coincide with mesh grid. Then
there is no need to do any interpolation. Using IB method means define the
velocity zero at the grids which are located in the square, after solving
momentum equations and before solving the poisson equations. Am I right?

2, When the boundary is not coincide with the mesh grid. We need to do
interpolation at the "ghost cell"( one layer grids between solid and
liquid). But How about the grids in the model which means solid. Do we just
define the velocity at the solid grid zero? Or we do not have to do anything to
do with them?
