| Foam::meshReaders | |
| Description | |
| A namespace for holding various types of mesh readers. | |
| Class | |
| Foam::meshReader | |
| Description | |
| This class supports creating polyMeshes with baffles. | |
| The derived classes are responsible for providing the protected data. | |
| This implementation is somewhat messy, but could/should be restructured | |
| to provide a more generalised reader (at the moment it has been written | |
| for converting pro-STAR data). | |
| The meshReader supports cellTable information (see new user's guide entry). | |
| Note: | |
| The boundary definitions are given as cell/face. | |
