Implicit time marching
WitrynaIV. Time-Marching Methods Time-marchingmethods convert the ODE’s produced by the spatial discretization to a system of algebraic equations. As mentioned earlier, explicit methods fail to deal with stiffness: the time step selection has to be based on the stability limits rather than physical time scales. Implicit A-stable methods are a much WitrynaExplicit and implicit methods are approaches used in numerical analysis for obtaining numerical approximations to the solutions of time-dependent ordinary and partial …

Witryna17 sty 2024 · Abstract In this work, adaptive explicit and implicit time marching techniques are proposed to analyze nonlinear dynamic models. In these time marching adaptive procedures, the adopted time integration parameters modify themselves along the solution process, in accordance with the varying properties and results of the model. WitrynaHowever, for convection-diffusion equations which are not convection-dominated, explicit time discretization will suffer from a stringent time step restriction for stability …
