个人看来,最经典最常用的网格质量判据,莫过于雅可比比率(Jacobian Ratio),也就是ICEM软件中的Determinant 2×2×2。 1. ICEM软件Determinant 2×2×2的定义 图1 ICEM软件的help文件原文对Determinant的定义 行列式Determinant(更恰当地定义为相对行列式)是雅可比矩阵的最小行列式除以雅可比阵的最大行列式的比值,即雅可比...
主要是单元形状的问题，试试更粗糙的单元或者更细的网格。比如2D的用三角形或者3D的用四面体。

A Jacobian ratio of 40 or less is acceptable. A negative Jacobian ratio causes SOLIDWORKS analysis to stop. Call this method after ICWStudy::CreateMesh to calculate the worst or highest Jacobian ratio among the elements of this mesh. See the SOLIDWORKS Simul...

And, this conversion ratio, theJacobian, works both ways. 这个转化率,也就是雅克比,两种情况下都成立。 2. The updating equation of imageJacobianmatrix is also given. 此外还给出了图像雅可比矩阵的递推公式。 3. VelocityJacobianmatrix and forceJacobianmatrix of the PMT are educed. ...
The usefulness and generality of the proposed technique is demonstrated by applying it to the estimation of the uncertainty for three different vision problems, namely self-calibratio- n, epipole computation and rigid motion estimation. 展开
