Explicit integration
Explicit and implicit methods are approaches used in numerical analysis for obtaining numerical approximations to the solutions of time-dependent ordinary and partial differential equations, as is required in computer simulations of physical processes. Explicit methods calculate the state of a system at a later time … See more Implicit methods require an extra computation (solving the above equation), and they can be much harder to implement. Implicit methods are used because many problems arising in practice are See more Consider the ordinary differential equation $${\displaystyle {\frac {dy}{dt}}=-y^{2},\ t\in [0,a]\quad \quad (2)}$$ with the initial condition $${\displaystyle y(0)=1.}$$ Consider a grid $${\displaystyle t_{k}=a{\frac {k}{n}}}$$ for 0 ≤ k ≤ n, that is, the time step is See more • Courant–Friedrichs–Lewy condition • SIMPLE algorithm, a semi-implicit method for pressure-linked equations See more WebExplicit time integration schemes are easy to implement and efficient for short-duration dynamic problems. However, for low strain rate and quasi-static problems, e.g., …
