Description
I have a .xdmf mesh file of a simple cube geometry with both the metadata and the definition of tetrahedral elements and node coordinates (heavy data) stored in the same plain text file using XML. Trying to open the original mesh of the entire cube geometry using the Xdmf3ReaderT caused Paraview to crash. I manually removed some element definitions from the file and found that the file is read correctly if the number of elements is smaller than same value (in my case it is roughly 425k).
The problem does not occur if the heavy data is stored in a .h5 file but here I am specifically asking for the ASCII encoding.
I am using Paraview 6.0.1 and observed the same behaviour on MacOS, Linux and Windows.
Find below two zipped mesh files with the NOT-OK.xdmf file containing just one element more than the OK.xdmf file. As the name suggests, the first file causes a crash whereas the second one doesn’t.
