Name

L2 Error Norm (L2ErrorNorm) — Use the root mean square of the components of the error.

Synopsis

L2ErrorNorm()

Details

Base class: ErrorNorm

Description

L2ErrorNorm is one way of computing the error in an element when using the ZZ_Estimator to drive finite element mesh adaptation. The relative percent error is

\mathrm{percent\ error}=\frac{\int_{\Omega}\,(\sigma^{*}-\sigma_{h})^{T}(% \sigma^{*}-\sigma_{h})\,d\Omega}{\int_{\Omega}\,\sigma^{*T}\sigma^{*}\,d\Omega% }\times 100

(6.149)

where $\sigma^{*}$ and $\sigma_{h}$ are the recovered stress and the finite element stress, respectively. The integral is over the area of the mesh element.
