Detailed Description

template<class Grid, class GridFct>
class AMDiS::GridFunctionMarker< Grid, GridFct >

Marker based on an indicator given as grid-function.

On each element the grid-function is evaluated in the barycenter. The returned values must be an integer (or convertible to an integer) indicating the desired refinement level of this element. The element is marked for refinement if the current level is < the desired level or coarsened, if >.

Template Parameters
GridAn Implementation of the Dune::Grid interface
GridFctA grid-function with Range convertible to int

Member Function Documentation

◆ markGrid()

Flag markGrid ( AdaptInfo adaptInfo)
overridevirtual

Mark element for refinement, if grid-function gridFct_ evaluates to a value larger than the current level and is marked for coarsening of the result is less than the current value.

Reimplemented from Marker< Grid >.
