- 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)
