Description
|
|
Reads .msh file as written by Gmsh.
|
|
|
|
Needs surface elements on mesh to be present and aligned with outside faces
|
|
of the mesh. I.e. if the mesh is hexes, the outside faces need to be quads
|
|
|
|
Note: There is something seriously wrong with the ordering written in the
|
|
.msh file. Normal operation is to check the ordering and invert prisms
|
|
and hexes if found to be wrong way round.
|
|
Use the -keepOrientation to keep the raw information.
|
|
|
|
Note: The code now uses the element (cell,face) physical region id number
|
|
to create cell zones and faces zones (similar to
|
|
fluentMeshWithInternalFaces).
|
|
|
|
A use of the cell zone information, is for field initialization with the
|
|
"setFields" utility. see the classes: topoSetSource, zoneToCell.
