Hi Frederic, have you been able to make progress on this issue?
I apparently ran into the same problem, which is quite frustrating since there is currently no way to concatenate more than 10 data items, despite having to independent implementations of the xdmf reader! I filed two bug reports for these issues in ParaView (not sure though if this is an ParaView/VTK or XDMF issue): https://gitlab.kitware.com/paraview/paraview/issues/17516 https://gitlab.kitware.com/paraview/paraview/issues/17517 Please feel free to add more information or test cases to these bug reports as well. @Andrew: I have never seen the "$0|$1" syntax in any xdmf documentation. When was this added and shouldn't this be mentioned in the xdmf wiki ( http://www.xdmf.org/index.php/XDMF_Model_and_Format#Function)?
