|
|
* @brief reads a dataset in Fluent GAMBIT neutral file format
|
|
*
|
|
* 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.
|
|

|
* Thanks to Jean M. Favre (CSCS, Swiss Center for Scientific Computing) who
|
|
* developed this class.
