Analysis of the variable step method of Dahlquist, Liniger and Nevanlinna for fluid flow

23 Jan 2020 Layton William Pei Wenlong Qin Yi Trenchea Catalin

The two-step time discretization proposed by Dahlquist, Liniger and Nevanlinna is variable step $G$-stable. (In contrast, for increasing time steps, the BDF2 method loses $A$-stability and suffers non-physical energy growth in the approximate solution.).. (read more)
