[Dune] Local Refinement - elementids are not assigned to newly generated mesh elements

[Dedner, Andreas]

Hi,

The grid does not know about the data and can not extend it to
new elements.
You are holding the data (getting it from the factory) and you are
responsible for prolongation to the new grid elements.

Best
Andreas

Hi,

I am generating mesh with gmsh and reading it with gmshreader and gridfactory, where every element is assigned an element id


typedef Dune::ALUSimplexGrid<dim,dim> Grid;
typedef Grid* GridPointer;

typedef Dune::GmshReader<Grid> GridReader;
typedef Dune::GridFactory<Grid> Factory;

std::vector<int> boundaryid;
std::vector<int> elementid;
GridReader gridreader;
Factory factory;
char ch;
gridreader.read(factory,gridfile,boundaryid,elementid,false,false);
GridPointer gridptr = factory.createGrid();
const Grid& grid = *gridptr;

then I am locally refining grid with mark and adapt. Now the newly generated elements are not assigned elementids of its parent elements. I find it logical to preserve elementids of parent elements.

Also in function mark(refCount, entity), refCount is not working. even if you put refCount>1 mark () marks element with 1. I reported this earlier but didnt get reply.
