Re: [deal.II] Re: Particle contact detection

2019-10-25 Thread Rene Gassmoeller

Hi Shahab,

I think this problem does not come from the vertex_to_cell_map but from 
the way you try to use it to find the neighbors. After calling 
vertex_to_cell_map you do not need to call 
GridTools::find_active_cell_around_point, because you already now the 
cells a vertex belongs to. Try the following modified code instead:


*
int iter3=0;
const auto v_to_c   = GridTools::vertex_to_cell_map(tr);

for (Triangulation<3>::active_cell_iterator cell = tr.begin_active(); 
cell != tr.end(); ++cell)

    {
        for (unsigned int v = 0; v < 
GeometryInfo<3>::vertices_per_cell; ++v)

        {
 for (const auto : v_to_c[cell->vertex_index(v)])
            std::cout<<"a neighbor of " << cell->id() <<"is : " << 
neighbor->id()<
        }
                    iter3++;
    }
**

You will notice that some cells appear more than once. That is because 
they are vertex neigbors to the current cell for more than one vertex. 
If you need to remove duplication you can collect the neighbors of the 
current cell in a std::set, which removes all duplications.


Hope that helps,

Best,

Rene

            std::cout<<"a neighbor of " << cell->id() <<"is : " << 
pcell->id()<
        }
                    iter3++;
    }
**
The problem is when I print the neighbors of each cell in the 
terminal, in the neighbors list for each cell only the cells with 
smaller ids comparing to the main cell are illustrated.
For instance: for the neighbors of cell 0_3:765 only the cells: 
0_3:742, 0_3:743, 0_3:760, 0_3:761, 0_3:746, 0_3:747 and 0_3:744 are 
shown.

Do you have any idea about the reason?

Best
Shahab

[deal.II] ASPECT 2.1.0 released

2019-04-30 Thread Rene Gassmoeller
We are pleased to announce the release of ASPECT 2.1.0. ASPECT is the 
Advanced
Solver for Problems in Earth’s ConvecTion. It uses modern numerical 
methods such

as adaptive mesh refinement, multigrid, and a modular software design to
provide a fast, flexible, and extensible mantle convection solver. ASPECT is
available from

https://aspect.geodynamics.org/

and the release is available from

https://geodynamics.org/cig/software/aspect/

and

https://github.com/geodynamics/aspect/releases/tag/v2.1.0

This release includes the following significant changes:

 * New: ASPECT has a new plugin system that allows to prescribe a fixed
   heat flux (instead of prescribing the temperature) at the model
   boundaries.
 * New: Compositional fields can optionally be advected with the melt
   velocity.
 * New: There is now a visualization postprocessor that outputs the
   compaction
   length, the characteristic length scale of melt transport.
 * New: ASPECT can optionally use the Geodynamic World Builder
   (https://github.com/GeodynamicWorldBuilder/WorldBuilder/) to create
   complex
   initial conditions for temperature and composition.
 * New: ASPECT can now read in a depth-dependent vs to density
   conversion file, which
   can be used with the included tomography model plugins.
 * New: ASPECT can now read in a depth-dependent initial temperature
   from file.
 * New: The ‘ascii data’ and ‘function’ boundary velocity plugins now allow
   velocities to be specified along spherical (up, east, north) unit
   vectors.
 * New: Added a visualization plugin that directly outputs the strain
   rate tensor.
 * New: ASPECT can now call PerpleX to calculate material properties, phase
   amounts and compositions on-the-fly. This model is provided as a
   proof-of-concept; more efficient procedures are required for
   production runs.
 * New: ASPECT now outputs a dynamically generated URL based on used
   features to
   ask people to cite appropriate papers.
 * New: ASPECT has two visualization postprocessors which calculate and
   output
   the grain lag angle and the infinite strain axis (ISA) rotation
   timescale,
   respectively. These two quantities can be used to calculate the grain
   orientation lag parameter of Kaminski and Ribe (G3, 2002).
 * Improved: The artificial diffusion term that is added in the entropy
   viscosity method to the temperature and composition equations is now
   computed
   as the maximum of the physical diffusion and entropy viscosity
   instead of the
   sum. This reduces numerical diffusion for the temperature field.
 * New: Compositional fields can now be prescribed to a value that is
   computed
   in the material model as an additional output at every time step.
 * Changed: The heat flux through boundary cells is now computed using the
   consistent boundary flux method as described in Gresho, et al.
   (1987), which
   is much more accurate than the previously used method.
 * New: ASPECT can now calculate gravity anomalies in addition to the
   geoid.
 * New: ASPECT now outputs a file named original.prm in the output
   directory
   with the exact content of the parameter it got started with.
 * New: Added basic support for a volume-of-fluid interface tracking
   advection
   method in 2D incompressible box models. The VoF method is an
   efficient method
   to track a distinct compositional field without artificial diffusion.
 * New: There is now an option to output visualization data as higher order
   polynomials. This is an improvement in accuracy and requires less
   disk space
   than the ‘Interpolate output’ option that was available before.
   However the
   new output can only be read by ParaView version 5.5 and newer and is
   therefore disabled by default.
 * New: Several new benchmark cases were added.
 * Many other fixes and smaller improvements.
