Ho Saad, You could try to produce a .plt file (a binary Tecplot format), and if your PV support it read this in. The benefits of plt files is size, and that it is a single file. With the PV support for plt. It used to be, that you needed to compile PV to use it, but I think now it is in the binaries (at least on Ubuntu). Cheers, Stan On 11.06.2022 11:24, Debbahi Saad wrote:

Hi All,
I'm on Nektar version 5.1.0, ending with datasets composed of moderate size files in numbers reaching few hundreds using the Incompresible Navier-Stokes Solver, I just want to use parallel FieldConvert to speed up the conversion process (which actually provide a real gain in speed) and produce a single vtu file, since opening *.pvtu format datasets gave an error in paraview-openmpi-5.9.1 , The command I'm using for parallel FieldConvert looks like this:
mpirun -n 16 FieldConvert -m mapping model.xml model_i.chk model_i.vtu
this creates n .vtu files under a .pvtu header, which as I reported earlier gives rise to this error:
ERROR: In /builddir/build/BUILD/ParaView-v5.9.1/VTK/IO/XML/vtkXMLPDataReader.cxx, line 315
vtkXMLPUnstructuredGridReader (0x55ffb1431450): File for piece 0 cannot be read.
Is it possible to produce one single .vtu file out of parallel FieldConvert ?
Thanks in advance, any help on this or workaround will be really appreciated,
Kind regards,
Saad
