Summary - ownersFather of ALUvertices does not find father
Task Type - Bug Report

Operating System - All
Severity - Low
Priority - Normal
Reported Version - SVN

Details - ownersFather and consequently positionInOwnersFather do not
work properly with ALUSimplexGrid<2,2>. Invariably there is no father
found. The following code reproduces the problem:

#ifdef HAVE_CONFIG_H
# include "config.h"     
#endif

#include <fstream>
#include <iostream>

#include <dune/grid/alugrid.hh>
#include <dune/grid/io/file/dgfparser/dgfalu.hh>

using namespace Dune;

int main (int argc, char *argv[]) try
{
	// The grid
	const int dim = 2;
	typedef ALUSimplexGrid<dim,dim> GridType;
	Dune::GridPtr<GridType> gridptr;
	gridptr = Dune::GridPtr<GridType>("data/square.dgf");
	GridType& grid = *gridptr;
	grid.globalRefine(3);


	typedef GridType::Codim<dim>::LevelIterator NodeLevelIterator;
	typedef GridType::Codim<dim>::LeafIterator NodeLeafIterator;
	typedef GridType::Codim<0>::Entity::EntityPointer ElementPointer;

	FieldVector<double,dim> posInOwnersFather;
	
	//~ NodeLeafIterator nodeLeafEnd = grid.leafend<dim>();
	//~ for (NodeLeafIterator nodeLeafIt = grid.leafbegin<dim>();
nodeLeafIt!=nodeLeafEnd; ++nodeLeafIt)
	//~ {
		//~ ElementPointer ownersFather = (*nodeLeafIt).ownersFather();
		//~ posInOwnersFather = (*nodeLeafIt).positionInOwnersFather();
	//~ }
	
	NodeLevelIterator nodeLevelEnd = grid.lend<dim>(3);
	for (NodeLevelIterator nodeLevelIt = grid.lbegin<dim>(3);
nodeLevelIt!=nodeLevelEnd; ++nodeLevelIt)
	{
		ElementPointer ownersFather = (*nodeLevelIt).ownersFather();
		posInOwnersFather = (*nodeLevelIt).positionInOwnersFather();
	}
			
	return 0;
}

catch (Exception e)
{
	std::cout << e << std::endl;
}
