Detailed Description

Select the mesh entities of one level of the spacetree.

The root of the spacetree, i.e. the bounding box of the whole domain, is level 0. Each further level splits the cells of its parent into three along each axis, i.e. a cell on level l has the size domain_size/3^l. The guards select exactly the vertices, faces and cells of this size, no matter whether they are refined further or not. If the mesh is coarser than the level somewhere, the guards do not hold there.

The markers do not know their level, so the guards compare the mesh size h() of the vertex, face or cell with the size of a cell on the selected level. Different to FineGridSelector, the selection does not depend on the refinement state, i.e. it is the same in each and every mesh sweep.

__init__()

peano4.api.toolbox.FixedResolutionGridSelector.FixedResolutionGridSelector.__init__	(		self,
		int	level,
			domain_size
	)

level: int Level of the spacetree, with 0 being the root.

domain_size: list of float Size of the computational domain along each axis, i.e. the same value as handed over to the project's global simulation parameters.

Member Function Documentation

_guard()

str peano4.api.toolbox.FixedResolutionGridSelector.FixedResolutionGridSelector._guard (   self )

protected

Compare each entry of marker.h() with the size of a cell on the selected level.

The tolerance is relative to this size, as the sizes become tiny on fine levels.
