Detailed Description

Mean value marking strategy.

Given local a posteriori estimates ${\eta_K}_{K\in\mathcal{P}}$ , of a domain partition $\mathcal{P}$ . The mean value $\overline \eta$ is computed as

$\overline\eta^2 = \frac{1}{\#\mathcal{P}} \sum\limits_{K\in\mathcal{P}} \eta_K^2$

.

Now given a choose value $\sigma\in (0,1$ all elements $K\in\mathcal{P}$ are marked for refinement for which

$\eta_K^2 \geq \sigma \overline\eta$

.
