My result file is vtu format file, and I try to open in using Paraview.
If data file size is small ( ~2GB) it opened well.
However if it’s size is more then 3 or 4 GB, I got some error message and can’t open it.
How can I solve it?

@1997best You didn’t state which OS you’re using. Windows perhaps?
There is a configuration problem when building VTK with the third party XML library, EXPAT, which means an incorrect stream size, type long, is used on 64 bit systems. For Mac and Linux it works because long is 4 bytes on 32 bit systems and 8 bytes on 64 bit systems, but on Windows long is always 4 bytes so the XML reader cannot go beyond 2Gb (the positive integral range).
