I'm just wondering how to import the cellDecomposition file into ParaView.
I want to visualize the decomposition of my fluid domain so I'm using decomposePar -cellDist.

Thanks

Hi!


Just open the reconstructed(original) mesh after decomposition. It should be there as a field.

Hi

When I open ParaView the cellDist field isnt there, reconstructPar gives me this:

Reconstructing FV fields

    Reconstructing volScalarFields

        p
        nut
        k
        epsilon

    Reconstructing volVectorFields

        U

    Reconstructing surfaceScalarFields

        phi

Reconstructing point fields

No point fields

No lagrangian fields

Nono. You don't need reconstructPar.
When you decompose with -cellDist, it'll write the cell distribution into the constant folder (maybe 0, I'm not 100% sure but I think into constant). But this list is for the original mesh (not decomposed). So after decomposition you just have to open the original mesh (you don't have to reconstruct), and don't skip the zero time!!! This is important!!! So uncheck this box in paraview. Then you can choose the cellDist in paraview.


And of course you won't see the field during reconstruction because this field is for the reconstructed mesh. So it is already reconstructed (actually it was never decomposed, but i hope you understand what i mean ).

Ahhh it's working now, I was scratching my head wondering why it wouldn't work.
