RETRACTED: Empirical analysis of the integration mechanism of explicit and implicit education on the ideological and political education and impact on mental health: The perspective of new media

Frontiers in Public Health, 2022
BackgroundEducation nowadays should be a combination of explicit and implicit education, which can effectively improve the effectiveness of ideological and political education, promote the development of ideological and political education in ...

A Godunov‐type finite‐volume solver for nonhydrostatic Euler equations with a time‐splitting approach

Journal of Advances in Modeling Earth Systems, 2017
A two‐dimensional conservative nonhydrostatic (NH) model based on the compressible Euler system has been developed in the Cartesian (x, z) domain. The spatial discretization is based on a Godunov‐type finite‐volume (FV) method employing dimensionally ...

A coupled implicit-explicit time integration method for compressible unsteady flows [PDF]

Journal of Computational Physics, 2019
This paper addresses how two time integration schemes, the Heun's scheme for explicit time integration and the second-order Crank-Nicolson scheme for implicit time integration, can be coupled spatially. This coupling is the prerequisite to perform a coupled Large Eddy Simulation / Reynolds Averaged Navier-Stokes computation in an industrial context ...

Comparative Study of Different Time Integration Algorithms for Solving Kinematic Problems

Modelling
This study selects five numerical methods: the explicit Leap-Frog scheme, the implicit Crank–Nicolson scheme, the explicit second-order Runge–Kutta scheme, the implicit Newmark-β scheme, and the implicit Bathe scheme.

Accelerated Runge-Kutta Methods

Discrete Dynamics in Nature and Society, 2008
Standard Runge-Kutta methods are explicit, one-step, and generally constant step-size numerical integrators for the solution of initial value problems. Such integration schemes of orders 3, 4, and 5 require 3, 4, and 6 function evaluations per time step ...

Large‐step explicit time integration via mass matrix tailoring

International Journal for Numerical Methods in Engineering, 2019
SummaryA method for tailoring mass matrices that allows large time‐step explicit transient analysis is presented. It is shown that the accuracy of the present tailored mass matrix preserves the low‐frequency contents while effectively replacing the unwanted higher mesh frequencies by a user‐desired cutoff frequency.
