Railway Engineering Science, 2022 In this work, a method is put forward to obtain the dynamic solution efficiently and accurately for a large-scale train–track–substructure (TTS) system. It is called implicit-explicit integration and multi-time-step solution method (abbreviated as mI-nE ...

Asymptotic Preserving time-discretization of optimal control problems for the Goldstein-Taylor model [PDF]
, 2013 We consider the development of implicit-explicit time integration schemes for optimal control problems governed by the Goldstein-Taylor model. In the diffusive scaling this model is a hyperbolic approximation to the heat equation.

Explicit parallel-in-time integration of a linear acoustic-advection system [PDF]
Computers & Fluids, 2012 The applicability of the Parareal parallel-in-time integration scheme for the solution of a linear, two-dimensional hyperbolic acoustic-advection system, which is often used as a test case for integration schemes for numerical weather prediction (NWP), is addressed.

Multi-Adaptive Time-Integration [PDF]
, 2004 Time integration of ODEs or time-dependent PDEs with required resolution of the fastest time scales of the system, can be very costly if the system exhibits multiple time scales of different magnitudes.

A phase-field model of thermo-elastic coupled brittle fracture with explicit time integration
, 2020 The phase-field method is a very effective way to simulate arbitrary crack nucleation, propagation, bifurcation, and the formation of complex crack networks. The diffusion-based method is suitable for multi-field coupling fracture problems. In this paper,

Discrete-time port-Hamiltonian systems: A definition based on symplectic integration [PDF]
, 2018 We introduce a new definition of discrete-time port-Hamiltonian systems (PHS), which results from structure-preserving discretization of explicit PHS in time.

An Explicit Meshless Point Collocation Solver for Incompressible Navier-Stokes Equations
Fluids, 2019 We present a strong form, meshless point collocation explicit solver for the numerical solution of the transient, incompressible, viscous Navier-Stokes (N-S) equations in two dimensions.
