Hybrid methods for direct integration of special third order ordinary differential equations

Abstract: In this paper we present a new class of direct numerical integrators of hybrid type for special third order ordinary differential equations (ODEs),y'''=f (x,y) ; namely, hybrid methods for solving third order ODEs directly (HMTD). Using the theory of B-series, order of convergence of the HMTD methods is investigated. The main result of the paper is a theorem that generates algebraic order conditions of the methods that are analogous to those of twostep hybrid method. A three-stage explicit HMTD is constructed.… Show more

“…To see if our proposed method agrees with some of the available numerical results, we firstly solve the problem in (23) using FDTHBS by fixing h ini = 10 −1 , x ∈ [0, 1] and varying the tolerances to have the same number of steps with the methods in [8,17]. The numerical results in Figure 9 confirm that the proposed method agrees well with the ones presented in [8,17].…”

“…However, there is a dearth of research in methods that solve higher-order stiff ODEs, especially third-order stiff ODEs. Most past research focused on the special and non-stiff third order ODEs as discussed in [10][11][12][13]. We, therefore, aim to develop an efficient direct method to provide numerical solutions for third-order ODEs.…”
