Dear all,

I would like to use mapFields to map the velocity field form a simulation containing only one region to a simulation containing multiple regions. Is this possible? Does somebody know how to do it?

On of the regions in the targer folder is the same size as the region in the source folder.

Any help will be appreciated.

Kind regards,

Steven

Fixed it myself, turned out it was not to hard

If anyone needs it let me know.

I would like to hear your solution. I'm mapping from mesh with two region onto a mesh with similar regions, but nothing seems to work.

Just take a look at this source code.

I added the -region option to the utility and changed:

  fvMesh meshTarget
        (
            IOobject
            (
                fvMesh::defaultRegion,
                runTimeTarget.timeName(),
                runTimeTarget
            )
        );

into:

  fvMesh meshTarget
        (
            IOobject
            (
                            regionName,
                            runTimeTarget.timeName(),
                            runTimeTarget,
                            Foam::IOobject::MUST_READ
                            /*   
                fvMesh::defaultRegion,
                runTimeSource.timeName(),
                runTimeSource*/
            )
        );

However, this will only work for consistent meshes and serial cases.

Thank you for the quick reply. Your solution works perfectly.

I added the region-thing also for the source, although now they have to have same names.

[samiam1000]

I know it's an old post, but I am having the same problems. I would like to map fields from a multiregion problem to the same multiregion one (I mean, same mesh and same regions' name and so on).

I tried to compile the archive you shared, but I get this error:

I am using OpenFOAM 2.2.1.

Any idea?

Thanks a lot,
Samuele

[Ahmed Khattab]

Did you compiled this utility after modification.

[stevenvanharen]

I think the 2.2.2 release has the options sourceRegion and targetRegion as standard in the utility mapFields, so no need to do anything yourself!

[samiam1000]

That is what I did, finally.

Thanks a lot,

Samuele
