Hello,

as I'm new in OF, so want to ask:
1. where shall I put this snippet of codes?
2. and when? before running a case?

thank you

-----------------------------------------------------------------------------
word zoneName = "zone1";
label zoneID = mesh.cellZones().findZoneID(zoneName);
if (zoneID == -1)
{
FatalErrorIn("cellZones") << "Cannot find cellZone " << zoneName << exit(FatalError);
}
labelList cells = mesh.cellZones()[zoneID];
