Two exponential wave integrator Fourier pseudospectral (EWI-FP) methods are presented and analyzed for the long-time dynamics of the Dirac equation with small potentials characterized by e ∈ ( 0 , 1 ] a dimensionless parameter. Based on the (symmet
In this paper a new hybrid semi-implicit finite volume / finite element (FV/FE) scheme is presented for the numerical solution of the compressible Euler and Navier-Stokes equations at all Mach numbers on unstructured staggered meshes in two and three

Laplace Poisson equations occur as field problems in many areas of engineering hence have received much attention. Relaxation methods awere developed originally in order to solve such field problems. In the linear case the governing equations (Laplac

In this report, we consider confined flow in a dual-porosity media coupled with free flow in embedded macrofractures and conduits. More specifically, the flow in dual-porosity media, which consists of both matrix and microfractures, is described by a

The 2.5D approach is an efficient tool for the dynamic analysis of half-space with longitudinally invariant properties. In this paper, a newly formulated 2.5D version of the NURBS-based isogeometric analysis (IGA) and the scaled boundary IGA (SBIGA)

In this paper, a high-order implicit-explicit flux reconstruction lattice Boltzmann method (FRLBM) is proposed for simulating viscous incompressible flows. The discrete velocity Boltzmann equation (DVBE) is solved by using a high-order flux reconstru

The purpose of this paper is to propose an optimization method for shape design of Auxetic Bending-Active Gridshells (ABAGs). A 2-dimensional auxetic structure has negative Poisson’s ratio for in-plane deformation. Positive Gaussian curvature distr

The manuscript describes a quadrature rule that is designed for the high order discretization of boundary integral equations (BIEs) using the Nystr\"{o}m method. The technique is designed for surfaces that can naturally be parameterized using a unifo

Based on the three-dimensional (3D) linear elastic theory without enforcing any plate assumptions, the scaled boundary finite element method (SBFEM) is proposed to solve the solution of the displacements, electrical potentials, critical buckling load

The ill-conditioned numerical system arising from an electromagnetic analysis is often due to the discretized curl–curl operator which has both zero eigenvalues and large ones inversely proportional to the square of the smallest feature size. In th
