// .NAME vtkGAMBITReader - reads a dataset in Fluent GAMBIT neutral file format
|
|
// .SECTION Description
|
|
// vtkGAMBITReader creates an unstructured grid dataset. It reads ASCII files
|
|
// stored in GAMBIT neutral format, with optional data stored at the nodes or
|
|
// at the cells of the model. A cell-based fielddata stores the material id.
|
|
|
|
// .SECTION Thanks
|
|
// Thanks to Jean M. Favre (CSCS, Swiss Center for Scientific Computing) who
|
|
// developed this class.
