implicit method performs significantly better than any of the sequential schemes implemented. This work aimed to build upon the findings in Wong et al. (2017) to develop a modified sequential method that can overcome the poor convergence in the previously described sequential strategies.

The Crank-Nicholson implicit method To obtain an algorithm that is unconditionally stable, we consider an implicit discretization scheme that results from using backward finite-differences for the time derivative.The corresponding difference equation is most conveniently obtained by approximating the diffusion equation at point (Xj,tn+i) Analogous to the forward-difference method previously

Digital implementation of sliding-mode control via the im-plicit method: A tutorial. International Journal of Robust and Nonlinear Control, Wiley, … The numerical integration of Hamiltonian systems with oscillating solutions is considered in this paper. A diagonally implicit symplectic nine-stages Runge-Kutta method with algebraic order 6 and dispersion order 8 is presented.

Implicit methods are used because many problems arising in practice are stiff, for which the use of an explicit method requires impractically small time steps to keep the error in the result bounded (see numerical stability). The implicit method is unconditionally stable, allowing the use of larger increment time steps. It is suitable for problems that tend to be highly linear, static, and quasi-static. Commercially available software for the application of implicit methods are: ABAQUS, ANSYS, and NASTRAN.

Let’s see how it compares to the explicit method Numerical Methods in Geophysics Implicit Methods Comparedwithexplicit and semi-implicit methods, the fully implicit method is usually more stable with a much larger time step size, which depends only on the accuracy requirement. An implicit method, in contrast, would evaluate some or all of the terms in S in terms of unknown quantities at the new time step n+1. Since new quantities appear on both the left and right side of the Q-equation, it is said to be an implicit definition of the new n+1 values. While implicit methods can allow signiﬁcantly larger timest eps, they do involve more computational work than explicit methods. Consider the forward method applied to u t =Au where A is a d ×d matrix. A popular method for discretizing the diffusion term in the heat equation is the Crank-Nicolson scheme.
