Refactorization of a variable step, unconditionally stable method of Dahlquist, Liniger and Nevanlinna
William Layton, Wenlong Pei, Catalin Trenchea
The one-leg, two-step time-stepping scheme proposed by Dahlquist, Liniger and Nevanlinna has clear advantages in complex, stiff numerical simulations: unconditional -stability f…

Analysis of the variable step method of Dahlquist, Liniger and Nevanlinna for fluid flow
William Layton, Wenlong Pei, Yi Qin +1
The two-step time discretization proposed by Dahlquist, Liniger and Nevanlinna is variable step -stable. (In contrast, for increasing time steps, the BDF2 method loses -stabi…
