A new family of explicit time integration methods
IOP Conference Series: Materials Science and Engineering, 2010 It is very promising for an integration method to possess unconditional stability and the explicitness of each time step simultaneously. For this purpose, a novel family of explicit methods, which can have unconditional stability, is developed and presented. For linear elastic systems, the numerical properties of the proposed family method are the same

An Advection Scheme using Paired Explicit Runge-Kutta Time Integration for Atmospheric Modeling
Gaoyuan qixiangIn this paper， a new numerical scheme was proposed to solve the advection equation in a multi-moment nonhydrostatic dynamical core.To guarantee the shape-preserving property， the limiting operations are devised for a hybrid discretization framework ...

Implementation of a damage model in a finite element program for computation of structures under dynamic loading [PDF]
Fracture and Structural Integrity, 2016 This work is a numerical simulation of nonlinear problems of the damage process and fracture of quasi-brittle materials especially concrete. In this study, we model the macroscopic behavior of concrete material, taking into account the phenomenon of ...

Explicit stencil computation schemes generated by Poisson's formula for the 2D wave equation
Engineering Reports, 2020 A new approach to building explicit time‐marching stencil computation schemes for the transient two‐dimensional acoustic wave equation is implemented. It is based on using Poisson's formula and its three time level modification combined with polynomial ...

Adaptive FEM with explicit time integration for the wave equation
Journal of Computational and Applied MathematicsStarting from a recent a posteriori error estimator for the finite element solution of the wave equation with explicit time-stepping [Grote, Lakkis, Santos, 2024], we devise a space-time adaptive strategy which includes both time evolving meshes and local time-stepping [Diaz, Grote, 2009] to overcome any overly stringent CFL stability restriction on ...

Implementation of multirate time integration methods for air pollution modelling [PDF]
Geoscientific Model Development, 2012 Explicit time integration methods are characterised by a small numerical effort per time step. In the application to multiscale problems in atmospheric modelling, this benefit is often more than compensated by stability problems and step size ...
