چکیده

Abstract. We consider a general class of systems of overdetermined differential-algebraic equations (ODAEs). We are particularly interested in extending the application of the symplectic Gauss methods to Hamiltonian and Lagrangian systems with holonomic constraints. For the numerical approximation to the solution to these ODAEs, we present specialized partitioned additive Runge– Kutta (SPARK) methods, and in particular the new class of (s, s)-Gauss–Lobatto SPARK methods. These methods not only preserve the constraints, symmetry, symplecticness of the flow, and variational nature of the trajectories of holonomically constrained Hamiltonian and Lagrangian systems, but they also have an optimal order of convergence 2s.

Beyond conventional Runge-Kutta methods in numerical integration of ODEs and DAEs by use of structures and local models ?

There are two parts in this paper. In the first part we consider an overdetermined system of differential-algebraic equations (DAEs). We are particularly concerned with Hamiltonian and Lagrangian systems with holonomic constraints. The main motivation is in finding methods based on Gauss coefficients, preserving not only the constraints, symmetry, symplecticness, and variational nature of traje...

Lagrange-d’Alembert SPARK Integrators for Nonholonomic Lagrangian Systems

Lagrangian systems with ideal nonholonomic constraints can be expressed as implicit index 2 differential-algebraic equations (DAEs) and can be derived from the Lagrange-d’Alembert principle. We define a new nonholonomically constrained discrete Lagrange-d’Alembert principle based on a discrete Lagrange-d’Alembert principle for forced Lagrangian systems. Nonholonomic constraints are considered a...

Iterative Solution of Nonlinear Equations for Spark Methods Applied to Daes

We consider a broad class of systems of implicit differential-algebraic equations (DAEs) including the equations of mechanical systems with holonomic and nonholonomic constraints. We approximate numerically the solution to these DAEs by applying a class of super partitioned additive Runge-Kutta (SPARK) methods. Several properties of the SPARK coefficients, satisfied by the combination of Lobatt...

Solution of Index 2 Implicit Differential-algebraic Equations by Lobatto Runge-kutta Methods

We consider the numerical solution of systems of index 2 implicit differential-algebraic equations (DAEs) by a class of super partitioned additive Runge-Kutta (SPARK) methods. The families of Lobatto IIIA-B-C-C-D methods are included. We show super-convergence of optimal order 2s−2 for the s-stage Lobatto families provided the constraints are treated in a particular way which strongly relies on...

Structure Preservation for Constrained Dynamics with Super Partitioned Additive Runge-Kutta Methods

A broad class of partitioned differential equations with possible algebraic constraints is considered, including Hamiltonian and mechanical systems with holonomic constraints. For mechanical systems a formulation eliminating the Coriolis forces and closely related to the Euler– Lagrange equations is presented. A new class of integrators is defined: the super partitioned additive Runge–Kutta (SP...
