Hello,

Is there any specific way OF orders/numbers the cells in different cellZones.

Are there any exceptions made while numbering?

I could not find any doc explaining this stuff.

Thanks

Okay.. so decided to answer this myself.

I don't know how the cell ordering takes place, but anyway I needed it in the code for doing some consistent operations using the cellIds.

Using some information from other threads, I found out a method to get the list of cellIds (of any set or zone) is:

cellSet test(mesh, name);
labelList cellIds = test.toc();

However, the toc() function returns the Ids in some random manner, and not in which they are present in polyMesh/sets/ .

Well, in case of averaging (or weighted averaging) the order does not matter.
But in my case, I needed them in the order.

I could not solve it, rather I found a workaround, by reading the cellIds from sets/ and use them for the purpose I intended.


If anyone has a better method, please feel free to post here.

Thanks,
Ashish Magar

The cell Ids of the cellZone depend on how the zone was defined. It is generally good practice to have this in sorted order, but any order is allowed provided that there are no duplicate ids.

If you want to create a sorted set of ids from a cellSet (which is inherently unordered), just specify the appropriate method:

cellSet test(mesh, name);
labelList cellIds(test.sortedToc());

You can also sort later if you want:

Foam::sort(cellIds);
