@@ -6,14 +6,6 @@ Provides structured and unstructured file writers for the VTK XML File Formats
that can be opened in the popular ParaView visualization application. Additionally
a file reader is provided to import VTK files into Dune grid and data objects.
## Requirements
For the management of the grids the
`dune-grid`
module is required. Additionally
for the data evaluation, the
`dune-functions`
module is used.
### Optional modules
For tests and examples
`dune-spgrid`
and
`dune-polygongrid`
are suggested, that
support structured grid data or special element types.
## Usage
The VTK writer works similar to the dune-grid
`VTKWriter`
. It needs to be bound
to a GridView and then data can be added to the points or cells in the grid.
