必应词典为您提供mass-lumping的释义,网络释义: 质量矩阵集中;质量集总;
When solving the wave equation with finite elements, mass lumping allows for explicit time stepping, avoiding the cost of a lower-upper decomposition of the large sparse mass matrix. Mass lumping on the reference element amounts to numerical quadrature. The weights should be positive for stable ...
研究的对象是两个质点,其mass matrix是对角矩阵,而这也是lumped mass matrix的特征。可以想见的是,...
aI know some schools use the American high school systemand.And there are also schools that offer European qualifications. 我知道有些学校使用美国高中systemand。并且也有提供欧洲资格的学校。[translate] amass lumping 许多混在一起[translate]
In this section and in the following, we shall study quadrilateral and hexahedral edge elements with mass-lumping. More precisely, this section will deal with the so-called first family of Nédélec’s (or edge) elements [92] on orthogonal meshes....
mass lumping procedure,中文的意思是质量集中,对应的还有个质量分布(其英文不知道是什么)。能否请教下...
The goal of this study is to evaluate the effect of mass lumping on the dispersion properties of four finite-element velocity/surface-elevation pairs that are used to approximate the linear shallow-water equations. For each pair, the dispersion relation, obtained using the mass lumping technique,...
4.2.1 Lumping of the Mass Matrix The bandwidth of the consistent mass matrix computed from Eq. (4.18d) depends on the node-numbering scheme. To reduce computational effort, we generally approximate it by a lumped (or diagonal) matrix; the same is also done for the consistent heat capacity ...
These elements lead to explicit methods after time discretization through the use of appropriate quadrature formulas which permit mass lumping. These formulas are constructed explicitly. Error estimates are provided for the corresponding semidiscrete problem. Finally, higher order finite difference time ...
