Sub-timing in fluid flow and transport simulations
TLDR
A sub-time stepping method is described for computational fluid dynamics problems that utilize implicit-type time marching procedures to resolve transients, particularly suitable for extensive simulations where large portions of a domain are temporally over-discretized.About:

Implicit subtime stepping for solving nonlinear flow equations in an integrated surface-subsurface system.
TL;DR: Application to several problems showed that implicit subtime stepping can significantly improve the simulation efficiency with minimal loss in accuracy and was successfully applied to enhance the computational efficiency of an integrated flow simulation in the San Joaquin Valley, California.

Multi-time-step explicit–implicit method for non-linear structural dynamics
TL;DR: It is shown that, within the framework of the Newmark family of numeric schemes, continuity of velocities at the interfaces enables the definition of an algorithm which is stable for all cases envisaged, and proposes to extend this to non-linear situations in the following cases.

The Laplace Transform Galerkin Technique: A time‐continuous finite element theory and application to mass transport in groundwater
TL;DR: Examination of the complex-valued, Laplace-domain concentration profiles reveal that they are generally smooth, well-behaved oscillatory functions compared to the profiles in the time domain, thus permitting the use of a coarse finite element grid.
