<P><FONT SIZE=2>Hi Andrea,<BR>
<BR>
that section is outdated - I'll provide a more up to date version<BR>
sometime soon. Sorry about that.<BR>
<BR>
In the last release we removed the configure flags<BR>
with-grid-dim, with-grid-type<BR>
they are not needed anymore and the include is also not needed - including<BR>
config.h is enough. To avoid problems with names GridType is now in<BR>
the namespace GridSelector.<BR>
In the finitevolume example you can see the correct usage:<BR>
GridPtr<GridSelector::GridType> gridPtr( dgfFileName.str() );<BR>
should do it.<BR>
<BR>
Then you can choose the grid manager while makeing the program:<BR>
make GRIDTYPE=ALUGRID_SIMPLEX GRIDDIM=2 GRIDWORLD=3<BR>
for example.<BR>
<BR>
Hope that helps along<BR>
Andreas<BR>

Subject: [Dune] Problems with DGF file and Dune::GridPtr<BR>
<BR>
Hi eveyone,<BR>
<BR>
I am trying to reproduce (with the stable version 2.1.1) some of the examples given in the Dune Grid Format (DGF), following the pdf manual on grids (page 23).<BR>
The problem arises when I want to use GridPtr.<BR>
<BR>
In particular, when I try to read a .dgf file, as in this line:<BR>
<BR>
GridPtr <GridType> gridPtr ("myfile.dgf");<BR>
<BR>
the compiler tells me that there is neither GridType nor GridPtr declared.<BR>
In particular, if I include:<BR>
<BR>
#include<dune/grid/io/file/dgfparser/dgfgridtype.hh><BR>
<BR>
I get this error:<BR>
<BR>
.../Dune_download/dune-grid-2.1.1/dune/grid/utility/gridtype.hh:24:6: error: #error "No grid type selected, typo in GRIDTYPE=...?"<BR>
<BR>
So, my questions are:<BR>
<BR>
1) Where (or how) do I have to put the definition of GRIDTYPE=ALUGRID_SIMPLEX ?<BR>
2) Which scope resolution operator should I use, once the proper inclusion had been made? Simply Dune::GridPtr ?<BR>
<BR>
Thanks in advance!<BR>
<BR>
Andrea<BR>
