Thank you for your quick reply. Indeed, I use the VTX reader and read the bp4 directory in paraview. So, if I understand well, it is not possible to use...

Ok, thank you for the reply. I do not think VTK supports this case but not sure.

I have another question, not with a direct link with that of this thread, but still deriving from it. I want to use polyhedron cells and there is no example...

I relaunch the discussion because after some tries, it does not seem possible to deal with polygons with adios2. Actually, I think that having different sizes is a major problem...

Thank you for your reply. I do not have such an example but it seems to me that the information given to adios2 must be structured differently as in a...

Ok, so to understand, you want a VTU file of a case? If so, it will be far different from the structure of XML VTU but I can give you...

Here an XML file representing a simple mesh with 2 cells [test2.zip](https://github.com/ornladios/ADIOS2/files/8098526/test2.zip) Here a VTU file representing the same mesh [test2vtu.zip](https://github.com/ornladios/ADIOS2/files/8098669/test2vtu.zip)

I think I might have an explanation but not sure, please, tell me what do you think. Adios2 simply write the arrays. So, when we write the connectivity array if...

Ok thank you for the reply. Hope you will find time to do that, I think it would be of great interest for adios2.

Thank you for your comment. However, the problem stems from the definition of the variables inside the considered software code that uses adios2 output. We need to know the number...
