This depends on your file format.
XDMF supports multiblock data, which if rendered all together, can look strange in Paraview.
Hello dokken,
me again 
thanks the med reader it is working great, one small question, that looking at your code i could not get to find a way, is there any way to get the original names for each face tag?
like āinletā etc. the tags that you are reading on the med file represents a group, and each group has its own name before exporting it, i am not sure if it is possible to recover this neames.
thanks in advance!
I didnāt initially add this functionality, but it should be possible to extend the reader to support this.
Please make an issue at:
with an appropriate mesh that we could test on, as this is the ānew packageā where I aim to do all io formats in the future:
i created an issue; read names of faces tags from `.med` file Ā· Issue #30 Ā· scientificcomputing/io4dolfinx Ā· GitHub
