We extend the monolithic convex limiting(MCL)methodology to nodal discontinuous Galerkin spectral-element methods(DGSEMS).The use of Legendre-Gauss-Lobatto(LGL)quadrature endows collocated DGSEM space discretizations ...

The task of identifying the quintic PH curve G^(0)“closest”to a given planar Bézier curve with or without prescribed arc length is discussed here using Gauss-Legendre polygon and Gauss-Lobatto polygon respectively....

A diagonal or lumped mass matrix is of great value for time-domain analysis of structural dynamic and wave propagation problems,as the computational efforts can be greatly reduced in the process of mass matrix inversi...

A lumped mass finite element formulation with consistent nodal quadrature is presented for improved frequency analysis of wave equations with particular reference to the Lagrangian elements with Lobatto nodes.For the ...
