Specifically, the two-dimensional Navier-Stokes equations are solved by a sequence of one-dimensional operators, each being explicit or implicit for streamwise or normal coordinate operation, respectively. The explicit operator employs a non-centered scheme due to MacCormack.

Application of the implicit MacCormack scheme to the parabolized Navier-Stokes equations. Abstract. MacCormack's implicit finite-difference scheme was used to solve the two-dimensional parabolized Navier-Stokes (PNS) equations.
This method for solving the PNS equations does not require the inversion of block tridiagonal systems of algebraic equations and permits the original explicit MacCormack scheme to be employed in those regions where implicit treatment is not : J. Lawrence, J.

Shu et al. proposed a numerical computation scheme of three dimensional incompressible Navier–Stokes equations in primitive variable form by DQ method.
A variation of the DQ method, called the Generalized Differential Quadrature (GDQ) was proposed by Lee et al.  and Zhu et al.  for study of mixed convection problems. For example, an unconditionally TVD backward Euler scheme is of the form u';+] + Mh'!:i>2 - h'£\n) = *j() This is a highly nonlinear implicit scheme.
An efficient procedure to solve this set of nonlinear equations is needed. The following focuses on linearized forms of the implicit scheme.
