Hi, When I try to duplicate or mirror the zones the duplicated zones don't appear in "zone style" unless I delete the original zones. Also, I noticed that the original zones have a star next to their number.
is there a way to make the original zones and the duplicated ones appear in "zone style"?
Thanks in advance

Hey Satarah,

I think the asterisks/stars mean that the data is coupled to a certain time step.

Regarding the duplicated zones that won't show in the 'Zone style' dialogue. What worked for me was go to Data>Extract>Blanked Zones... Then answer Yes on the Question 'Blanking is not active. Do you want to continue?'. Select the duplicate zone and click OK. It will now appear in the 'Zone style' dialogue as 'Extracted something'

Hope this will work for you.

Cheers, Pieter

A better solution is to use "Edit Time Strands". The asterisk indicates that the data are being treated as "transient" and the duplicated zone is considered to be the same object at the same solution time - which is why you can't see it in Zone Style.

Go to Edit Time Strands and - for the newly duplicated zones - assign a new Strand ID.

So what is a Strand ID? It's a number that identifies a series of zones through time as being the same object. So consider a transient simulation of an aircraft where you have a fuselage, wing, and tail. You'd identify all the "fuselage" zones through time as Strand 1, wing as Strand 2, and tail as Strand 3. In this case you'll only have three items in Zone Style as defined by the strand ID.

To recap - when duplicating zones, the strand ID is retained which means that the duplicated zone is bundled in the same line in Zone Style. To get the duplicated zone to show up in a new line in Zone Style it needs a different Strand ID than the original zone.
