A question heard from many users is how to find out quickly what is the NAME of a zone, given the ID of that zone. The reasons for having the ID of a zone, but not the name of the zone may be a warning / error message displayed by ANSYS Fluent about a given zone (i.e. they contain information about the type and the ID of the zones, e.g. “reversed flow in 76 faces on pressure-outlet 3”). Type the text command: /def/bc/zone-name ID then press ENTER twice. In between, ANSYS Fluent will display the name of the zone between [], as in the following example, where the name “fan-porous” of the zone with the ID of 2 is displayed: /def/bc/zone-name 2 Zone Name [fan-porous]
