- in various situations with mesh regions it is also useful to
filter out or remove the defaultRegion name (ie, "region0").
Can now do that conveniently from the polyMesh itself or as a static
function. Simply use this
const word& regionDir = polyMesh::regionName(regionName);
OR mesh.regionName()
instead of
const word& regionDir =
(
regionName != polyMesh::defaultRegion
? regionName
: word::null
);
Additionally, since the string '/' join operator filters out empty
strings, the following will work correctly:
(polyMesh::regionName(regionName)/polyMesh::meshSubDir)
(mesh.regionName()/polyMesh::meshSubDir)
