Higher Order Triangular Finite Elements with Mass Lumping for the Wave Equation
Solving the wave equation by a C o finite element method requires to mass-lump the term in time of the variational f6rmulation in order to avoid the inversion of a n-diagonal symmetric matrix at each time-step of the algorithm. One can easily get this mass-lumping on quadrilateral meshes by using a h-version of the spectral elements, based on Gauss-Lobatto quadrature formulae but the equivalent...
متن کاملImproved Estimates of Kinematic Wave Parameters for Circular Channels
The momentum equation in the kinematic wave model is a power-law equation with two parameters. These parameters, which relate the discharge to the flow area, are commonly derived using Manning’s equation. In general, the values of these parameters depend on the flow depth except for some special cross sections. In this paper, improved estimates of the kinematic wave parameters for circular chan...
متن کاملStudy of the Depuration Capacity of a River, Considering the Propagation of a Dynamic Wave
This paper intends to evaluate the capacity of self-purification of a river, on the influence of a dynamic wave. Therefore, it was developed a mathematical modeling, where it were used Hydrodynamic Equations, combined with the Advective Diffusive Equation, to describe the behavior of the transport processes in urban rivers. The results showed that the hydraulic parameters play an important game...
متن کاملCurvilinear wave-equation angle transform: Caustics, turning rays, absence of kinematic artifacts
Migration of seismic reflection data to common image-point gathers is an integral part of both migration velocity analysis (MVA) and amplitude (AVA) analysis. Its applicability in complex geology depends on whether these gathers will be artifact free, and is related to the formation of caustics and turning ‘rays’ due to the heterogeneity of the velocity model used. Here, we discuss an angle tra...
متن کاملIs the Pollution Effect of the FEM Avoidable for the Helmholtz Equation Considering High Wave Numbers?
The development of numerical methods for solving the Helmholtz equation, which behaves robustly with respect to the wave number, is a topic of vivid research. It was observed that the solution of the Galerkin finite element method (FEM) differs significantly from the best approximation with increasing wave number. Many attempts have been presented in the literature to eliminate this lack of rob...
