The Accuracy of the Fractional Step Method [PDF]
SIAM Journal on Numerical Analysis, 1999 It is known from the sixties that fractional step methods have significant loss of accuracy in the case of Dirichlet conditions and simple parabolic problems. The authors consider a special variant of such methods for solving initial-boundary value problems associated with nonstationary Navier-Stokes systems with two space variables in the first ...
