I am using ubuntu 20.04 and installed ParaView 5.8. It can load single .data file from my ParaDiS simulation. It crashes when loading the second (the same happens for loading a result serie).
Could anyone help me with that? Thanks a lot!
Two data files are like the following
[rs0001.data](https://discourse.paraview.org/uploads/short-url/f6jZsWtPotDI36WxhRI1xjhZDv7.data) (442.4 KB)
[rs0002.data](https://discourse.paraview.org/uploads/short-url/wregI0KQDairXSCTlmDOhNoS55O.data) (442.4 KB)
The error message is the following
using avtparaDISFileFormat::avtparaDISFileFormat version 2.3.4
Loguru caught a signal: SIGSEGV
