There are many possible approaches for automatically selecting the time step in numerical simulations. One intuitive strategy is to estimate the time step estimate based on the solution’s dynamics, opting …

Based on the formulation to calculate material sound velocity and time-step requirement, the larger the material’s mass is, the larger the required time-step can be.

The need for a time step restriction is true of all explicit methods. By contract, implicit methods often have a much better time step restriction that makes them more suitable even though they require a …

der, A- and G- stable for arbitrary, non-uniform time steps. The DLN method thus has strong potential for use in adaptive co. es, but its adaptive step size selection is little explored. This report develops two …

This section gives more details about the relation between the network simulation time step and real-time output time step, addressing two issues: instrument transformer and circuit breaker model …

In this section we want to investigate methods which allow us to estimate an error and then use this error to decide if the time step can be increased or if it should be decreased.

In the present paper we have demonstrated the effectiveness of adaptive time-stepping (ATS) to accel-erate convergence of false transient time-stepping to steady-state solutions of an implicit …
