Detailed Description

template<class TGrid, class TAPosition>
class ug::FracturedMediaRefiner< TGrid, TAPosition >

This class takes special care for degenerated fractures during refinement. Degenerated faces are refined using anisotropic refinement, so that their degenerated sides are not refined.

Currently this only works in 2d.

Todo:

Add support for degenerated volumes

Use a IsDegenerated callback instead of thresholds

◆ mark()

template<class TGrid , class TAPosition >
bool ug::FracturedMediaRefiner< TGrid, TAPosition >::mark ( Face *  f,
RefinementMark  refMark = RM_REFINE

virtual

Marks a face for refinement.

Uses the degenerated-edge-threshold to determine, whether the face is a fracture-face or not. Make sure to specify a position attachment before marking any elements.

◆ set_aspect_ratio_threshold()

template<class TGrid , class TAPosition >
void ug::FracturedMediaRefiner< TGrid, TAPosition >::set_aspect_ratio_threshold ( number  threshold)

if the aspect ratio is smaller then the given threshold, the element is considered a fracture element.

◆ set_position_attachment()

: replace this with a callback
