Constructor & Destructor Documentation

◆ RefinedMesh() [1/3]

RefinedMesh::RefinedMesh ( Mesh const &  cmesh,
std::vector< bool > const &  ibref 
)

Constructs a refined mesh according to the marked elements in ibref.

If the vector ibref has size 0 then all elements will be refined.

Parameters
[in]cmeshoriginal mesh for coarsening.
[in]ibrefvector containing True/False regarding refinement for each element

Definition at line 816 of file geom.cpp.

◆ RefinedMesh() [2/3]

RefinedMesh::RefinedMesh ( Mesh const &  cmesh)
inlineexplicit

Constructs a refined mesh by regulare refinement of all elements.

Parameters
[in]cmeshoriginal mesh for coarsening.
