| Foam::createShellMesh | |
| Description | |
| Creates mesh by extruding a patch. | |
| SourceFiles | |
| createShellMesh.C | |
| Extrudes into thickness direction. | |
| - bottom faces originate from reversed original faces (have turning index) | |
| - top faces originate from original faces (no turning index) | |
