In this section, special practices related to the discretization of the momentum and continuity equations and their solution by means of the pressure-based solver are addressed. Information is organized into the following subsections:
These special practices are most easily described by considering the steady-state continuity and momentum equations in integral form:
 | (23–39) |
 | (23–40) |
where 
is the identity
matrix, 
is the stress tensor, and 
is the force vector.
