Grids

The following is a list of available Dune grids. Some of them are just wrapper to external libraries.

Name Module External
AlbertaGrid dune-grid yes
ALUGrid dune-alugrid no
CurvilinearGrid dune-curvilineargrid no
FoamGrid dune-foamgrid no
OneDGrid dune-grid no
P4estGrid dune-p4estgrid yes
PolygonGrid dune-polygongrid no
SPGrid dune-spgrid no
UGGrid dune-uggrid yes
YaspGrid dune-grid no

Metagrids

Metagrids wrap other Dune grid, providing facilities such as replacing geometry, glueing domains, etc.

Name Module
GeometryGrid dune-grid
PrismGrid dune-prismgrid
CacheItGrid dune-metagrid
CartesianGrid dune-metagrid
FilteredGrid dune-metagrid
IdGrid dune-metagrid
MultiSPGrid dune-metagrid
ParallelGrid dune-metagrid
SphereGrid dune-metagrid
GridGlue dune-grid-glue
MultiDomainGrid dune-multidomaingrid
SubGrid dune-subgrid

Features

These are the features provided by the grid via its Dune interface – note that these may be different from the features provided by the underlying external grid library.

GridType Dimensions Structured Notes
AlbertaGrid<dim,dimw> 1≤dim≤3, 1≤dimw≤9, dim≤dimw unstructured Can’t have two grids of different dimw in the same binary
ALUGrid<dim,dimw,simplex,conforming> 2≤dim≤dimw≤3 unstructured
ALUGrid<dim,dimw,cube,nonconforming> 2≤dim≤dimw≤3 unstructured
ALUGrid<dim,dimw,simplex,nonconforming> 2≤dim≤dimw≤3 unstructured
GeometryGrid<HostGrid> hostdim=dim≤dimw unstructured
OneDGrid dim=dimw=1 unstructured
UGGrid<dim> 2≤dim=dimw≤3 unstructured UG with MPI: no more than one grid object of the same dim may be live at any given time
SPGrid<ct,dim,rs,comm> dim=dimw structured
YaspGrid<dim> dim=dimw structured lower left corner fixed to 0.
YaspGrid<dim, EquidistantOffsetCoordinates<ctype, dim> > dim=dimw structured arbitrary lower left corner (introduced in 2.4)
YaspGrid<dim, TensorProductCoordinates<ctype, dim> > dim=dimw structured (introduced in 2.4)
