mergeMeshes
 
Hi all,

I try to merge 4 identical (in size) meshes with mergeMeshes. The interfaces match perfectly. Mesh #1 and mesh #2 merge perfectly. Then I use stitchMesh and renumberMesh. Everything works perfectly. Mesh #3 and mesh #4 merge perfectly. But, mesh #1 and mesh #3 do not merge :

Code:
--> FOAM FATAL ERROR:
Illegal zoneID 1 for face 2675997

    From function resetZones(const polyMesh&, polyMesh&, labelListList&labelListList&, labelListList&)
    in file polyTopoChange/polyTopoChange/polyTopoChange.C at line 1587.

FOAM aborting
each mesh has 450 000 cells. The final mesh should have 1 800 000 cells.

Any advises?
Pascal

Hi Pascal!

Could you solve this? I have got the same problem.

Hi Sebastian,

No... By the way which version you have? The error message I got was with OF 1.6, but everything worked fine with OF 1.6.x.

Regards,

Pascal

Hi Pascal,

well, okay. I am using 1.6. But I think I can solve that problem on a different way. Anyway, thanks :)


Best Regards,
Sebastian

Hi,

I ran into the same error... went away by removing faceZones files in polyMesh/

That sucks a bit since I need those zones.... and strange thing is that other meshes I joined to the same mesh contained both cell- and faceZones without causing trouble... could not see any reason why this particular mesh could not contain faceZones.

Edit:
Above comment concerned OF 17.0. Repeating exactly the same thing in OF 1.5-dev gave no such errors.
Before mergeMeshes all mesh parts were prepared in 1.7.0 using fluent3DmeshToFoam and setSet and setsToZones. Only 1.5-dev could take it from there it seems.
I did not try other versions.
In cases 1.7.0 could merge with *Zones, they got randomly mixed up.
