In this paper, we present a general conservative eighth-order compact finite difference scheme for solving the coupled Schrödinger-KdV equations numerically. The proposed scheme is decoupled and preserves several physical invariants in discrete sens

In this paper, we consider the numerical solution of an evolutionary variational–hemivariational inequality arising in a dynamic contact problem. The material is assumed to be viscoelastic with short memory. The contact is featured by a normal damp

In this paper, a systematic algorithm of spline element method allowing multiple level hanging nodes on triangular mesh is proposed. The classical smoothness condition of the piecewise polynomials on triangular mesh is generalized to the case of mesh

The goal of the arterial graft design problem is to find an optimal graft built on an occluded artery, which can be mathematically modeled by a fluid based shape optimization problem. The smoothness of the graft is one of the important aspects in the

We propose a p -version two level method for the spline solutions of the Navier-Stokes equations in stream function formulation. The new two level method can significantly accelerate the corresponding one level method, especially when the degrees of

The C 1 $C^{1}$ spline spaces with degree d ≥ 5 $d\geq 5$ over given triangulations are implemented in the framework of multi-variate spline theory. Based on this approach, two-level methods are proposed by using various order spline spaces for the

Variational–hemivariational inequalities and hemivariational inequalities form a powerful mathematical tool in modeling and studying problems in science and engineering where non-smooth, non-monotone and multi-valued relations among different physi

This paper represents a sequel to the previous one, where numerical solution of a quasistatic contact problem is considered for an elastic body in frictional contact with a moving foundation. The model takes into account wear of the contact surface o

In this work, we present a conservative method to solve the coupled Schrödinger-KdV (CSK) equations. The CSK equations are discretized in space by Fourier spectral collocation method and exponential time differencing with three-layer implicit scheme
