Hi all,

I have a question about the renumberMesh utility since it may perform different renumbering but I can't find the origin.

I created a volScalarField called meshid whose internalfield value is the cellID:

Code:
internalField  nonuniform List<scalar>
40483
(
0
1
2
...
40480
40481
40482
);
Then I run

Code:
renumberMesh -overwrite
and looking at the result, I found that renumbering is exactly similar between OF6 and OF7 on my laptop but results are différent on my other computer (OF6 remains similar but OF7 give different renumbering).

Looking at the compiler options, I found that all OF versions are compiled with options

Code:
linux64GccDPInt32Opt
Anyone has an idea to explain the difference in renumbering ?

Thanks,

Pierre

Hi all,


I found the explanation. There are some issues in openfoam-version 7 of July 2019 which has been corrected (patched) in th version of September 2019.

The pre-compiled packages are correctly updated but the source available on the website www.openfoam.org are from July 2019 and not updated.

This should be updated on the website to avoid similar issues for of-user who wants to compile openfoam on their computers.

Pierre
