Hi everybody

The output of my parallel cfd code is in Hdf5 and Xdmf.
My problem is that paraview displays the mesh partitions.
I want to remove it to just see the computation domain.
I put a picture, it is better to understand my problem.
the computational domain is a cube and I use 3 processors (so 2 slaves -> 2 partitions)

There is a solution with paraview to remove the mesh partition ?
like a filter ?
or I have to modify the hdf5 implementation ?

thank you very much

Greetings Hadrien,

We have this problem when using ParaView's internal OpenFOAM reader, when loading decomposed meshes. I know I've seen a question about this in the OpenFOAM forum, but I can't find it
Either way, I've learned to ignore it

Nonetheless, you can try looking for and/or asking this in ParaView's User mailing list: http://www.paraview.org/mailman/listinfo/paraview

Good luck!
Bruno

Thank you Bruno for your answer.
I will check in the open foam forum.
I sent also this question to the HDF5 groups mailing list, I am waiting an answer.
If I find the solution I will put it in this forum.
Thank you Bruno

I forward the answer
-------------------------------------------------------------
Hi Hadrien, Does your output consist of partition(zone) connectivity information or any information about nodes that are on internal boundaries? If the simulation can write out an additional mask array to indicate the nodes on the internal boundaries, then you could use threshold within ParaView to remove internal boundaries. Best, George

This is due to the lack of support for ghost points (or shared points) in ParaView. Discussions about adding its support have arisen several times in the PV list
http://markmail.org/thread/tgf6rqulpnxelewp
http://markmail.org/thread/hpikotbcwmkr75po
and I would be willing to add the ghost point feature to the reader. But I still do not hear that the support is in.

Hi, I have the same problem when importing a tecplot file format in paraview, that is, I see all the internal block structure. I have used the filter "Merge blocks" and it seems to work!
