Name
L2 Error Norm (L2ErrorNorm) — Use the root mean square of the components of the error.
Synopsis
L2ErrorNorm()
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
![\[
\mathrm{percent\ error} = \frac{\int_\Omega\,
(\sigma^* - \sigma_h)^T
(\sigma^* - \sigma_h)\, d\Omega}
{\int_\Omega\,\sigma^{*T} \sigma^*\,d\Omega} \times 100
\]](equations/6.5.2-eq-25.gif)
where
and
are the recovered stress and the finite element stress,
respectively. The integral is over the area of the mesh element.
