Namespace
|
|
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 generalized 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.
