Detailed Description

AMR projectors.

Function Documentation

◆ new_mesh()

template<size_t Dim>
Mesh< Dim > amr::projectors::new_mesh ( const Mesh< Dim > &  current_mesh,
const std::array< Flag, Dim > &  flags,
const Element< Dim > &  element,
const std::unordered_map< ElementId< Dim >, Info< Dim > > &  neighbors_info 
)

Computes the new Mesh of an Element after AMR.

Details

The returned Mesh will be that of either element or its parent or children depending upon the flags. If an Element is joining, the returned Mesh will be that given by amr::projectors::parent_mesh; otherwise it will be given by amr::projectors::mesh

◆ parent_mesh()

template<size_t Dim>
Mesh< Dim > amr::projectors::parent_mesh ( const std::vector< Mesh< Dim > > &  children_meshes)

Given the Meshes for a set of joining Elements, returns the Mesh for the newly created parent Element.

Details

In each dimension the extent of the parent Mesh will be the maximum over the extents of each child Mesh
