Boundary condition in pressure equation
 
Hello, i have a doubt the boundary condition that Fluent uses for the pressure equation.

In the user's guide, section 25.4.1, Pressure Interpolation Scheme, it's written:

"Another source of error is that FLUENT assumes that the normal pressure gradient at the wall is zero..."

Is it referred to the use of this particular interpolation scheme or it is the only one boundary condition for the pressure equation?

Thanks a lot
