Front-end for the grid manager of the finite element toolbox UG.
This is the implementation of the grid interface using the UG grid management system (http://www.iwr.uni-heidelberg.de/frame/iwrwikiequipment/software/ug). UG provides conforming grids in two and three space dimensions. The grids can be mixed, i.e. 2d grids can contain triangles and quadrilaterals and 3d grids can contain tetrahedra and hexahedra and also pyramids and prisms. The grid refinement rules are very flexible. Local adaptive red/green refinement is the default, but a special method in the UGGrid class allows you to directly access a number of anisotropic refinements rules. Last but not least, the UG grid manager is completely parallelized, and you can use boundaries parametrized by either analytical expressions or high-resolution piecewise linear surfaces.
To use this module you need the UG library. See the DUNE installation notes on how to obtain and install it.
In your Dune application, you can now instantiate objects of the type UGGrid<2> or UGGrid<3>. You can have more than one, if you choose. It is even possible to have 2d and 3d grids at the same time, even though the original UG system never intended to support this!
See the documentation for the factory class GridFactory<UGGrid<dimworld> > to learn how to create UGGrid objects.
Please send any questions, suggestions, or bug reports to the Dune mailing list dune@ dune -proj ect. org
For installation instructions see http://www.dune-project.org/external_libraries/install_ug.html .
