Thank you Timo,
but as I understand, also from the return message:
Dune reported error: GridError
[assertGeometryType:/usr/local/include/dune/alugrid/3d/gridfactory.hh:438]:
Only cube geometries can be inserted into ALUGrid< 3, 3, cube, refrule >.
only 3D geometries can be handled by Alugrid, is it correct?
Maybe UGGrid can manage also 2d unstructured geometries? In this case it
is advisable to use it?
Indeed, which is the main difference between these packages?
Best regards,
Lorenzo

Hi Lorenzo,
You download
(https://gitlab.dune-project.org/extensions/dune-alugrid), configure,
and compile dune-alugrid, like any other Dune module.
You can set Dune::ALUGrid as grid manager, by setting the "Grid"
property in Dumux to this type.
(1) For a simple rectangular mesh with simplices, just use the
structured grid factory through the DuMux input file by putting
something like this in your input file:
[Grid]
LowerLeft = 0 0 0
UpperRight = 1 1 1
Cells = 10 10 10
CellType = Simplex
(2) For more complicated simplex grids you typically generate the mesh
with gmsh (http://gmsh.info/) which will produce an *msh file. You can
tell ALUGrid to use this file through the input file
[Grid]
File = mygrid.msh
For more informations on grid managers and how to use them, please
have a look at the Dumux handbook
(http://www.dumux.org/documents/dumux-handbook-2.12.pdf).
Best wishes
Timo

Good morning developers and users,
I'd like to ask how to use alugrid. Where can I find some
examples/references just to create simplices mesh even for simple
rectangular geometries.
Thank you,
Lorenzo
