Detailed Description

template<class GridType>
class Dune::StarCDReader< GridType >

File reader for the Star-CD format.

Reads grid data described by the Star-CD format and fills an empty grid with the data. Uses the grid creation methods described in "How to Write a File Reader for UGGrid Objects".

Two files fileName.vrt and fileName.cel have to be present. The file fileName.vrt contains the coordinates of the nodes, each row having the format

idx x-coordinate y-coordinate z-coordinate

The file fileName.cel contains the data of the volume and possibly the boundary elements, each row having the format

idx node1 node2 ... node8 material/boundaryId flag1 flag2

The flags flag1 and flag2 appear to be always identical to 1 in case of a volume element and to 4 in case of a boundary element. The element types simplex, pyramid, prism, and cube are supported:

  • For cubes, the indices node1 ... node8 are what you expect them to be.
  • For simplices, node3 and node4 are identical, as well as node5 ... node8.
  • For pyramids, node5 ... node8 are identical.
  • For prisms, node3 and node4 are identical, as well as node7 and node8.

This reader only supports three-dimensional grids.

Currently no boundary element data is passed to grid.
