Hi Alex!<br>
Great to hear you are using Dune. A structured cube UGGrid is most
easily<br>
created using the StructuredGridFactory class (only available in the
svn --<br>
not in dune 2.0). Here is a code snippet:<br>
<br>
const int dim = 3;<br>
typedef UGGrid<dim> GridType;<br>
<br>
FieldVector<double,dim> lowerLeft(0);<br>
FieldVector<double,dim> upperRight(1);<br>
array<unsigned int, dim> elements;<br>
std::fill(elements.begin(), elements.end(), 10);<br>
<br>
StructuredGridFactory<GridType> factory;<br>
shared_ptr<GridType> grid =
factory.createSimplexGrid(lowerLeft, upperRight, elements);<br>
<br>
You can write the grid into a VTK file using the following two lines:<br>
<br>
VTKWriter<GridType::LeafGridView>
vtkWriter(grid->leafView());<br>
vtkWriter.write("my_filename");<br>
<br>
BTW, what's your thesis about?<br>
<br>
Best,<br>

I am Master's student, new to DUNE. I have just started my Master's
Thesis using DUNE. I want to create a 3D grid of cubes using DUNE and
then visualize it using Paraview with the VTKWriter. But I have no clue
how to go about it. I read through the dune-grid-howto documentation
and also went through the DGF Parser and stuff. But I am not sure which
is the starting point.<br>
<br>
Can someone be kind enough to suggest me how to create and visualize a
grid in DUNE. Either by using the DGF Parser or with the UG Grid and
then visualize the grid?<br>
<br>
Thanks,<br>
Alex<br>
