متن کاملOn A Posteriori Error Estimates
Consider a sequence {xn}n—Q in a normed space X converging to some x* £ X. It is shown that the sequence satisfies a condition of the type ||x* -x„|| < oi||xn xn_¡\\ for some constant a and every n > 1, if the associated null sequence {e„}„=q, en = x* — xn, is uniformly decreasing in norm or if it is alternating with respect to any ordering whose cone of positive elements is acute.
متن کاملAnisotropic mesh adaptation based upon a posteriori error estimates
An anisotropic mesh adaptation strategy for finite element solution of elliptic differential equations is considered. The adaptation method generates anisotropic adaptive meshes as quasiuniform ones in some metric space. The associated metric tensor is computed by means of a posteriori hierarchical error estimates. A global hierarchical error estimate is employed in this study to obtain reliabl...
متن کاملInterpolation Error Estimates for Edge Elements on Anisotropic Meshes
The classical error analysis for the Nédélec edge interpolation requires the so-called regularity assumption on the elements. However, in [18], optimal error estimates were obtained for the lowest order case, under the weaker hypothesis of the maximum angle condition. This assumption allows for anisotropic meshes that become useful, for example, for the approximation of solutions with edge sing...
متن کاملEdge residuals dominate a posteriori error estimates for linear finite element methods on anisotropic triangular and tetrahedral meshes
In [10, 11] D. Yu proved that on a uniform square grid the error of the finite element method is controlled by either the element residuals or the edge residuals, i.e. jumps of the normal derivative across interelement boundaries, depending on whether the degree of the finite element functions is even or odd. The proof strongly relies on the uniformity of the grid, the tensor-product structure ...
