Numerical analysis of a bdf2 modular grad-div Stabilization method for the Navier-Stokes equations
Y. Rong, J. A. Fiordilino
A second-order accurate modular algorithm is presented for a standard BDF2 code for the Navier-Stokes equations (NSE). The algorithm exhibits resistance to solver breakdown and inc…

On the determination of the grad-div criterion
V. Decaria, W. Layton, A. Pakzad +3
Grad-div stabilization, adding a term -gamma grad div u, has proven to be a useful tool in the simulation of incompressible flows. Such a term requires a choice of the coefficient…
