Solving the incompressible Navier-Stokes equations numerically is a unique challenge because of the absence of direct link between pressure and density. As a workaround, the pressure equation must be derived from the velocity field and corrected in each iteration to ensure divergence free condition is satisfied.

Marker-and-cell (MAC) algorithm is the most common algorithm used to numerically solve in compressible Navier-Stokes equations. What is the main characteristic of this algorithm?
