VTK file names sorting problem

Hi, I got these outputs from the code, but when I open with VTK, it doesn’t group to one, and the sorting is not in ascending order, what can I do in Paraview? and what is the suggestion for changing the source code output?

Thank you!

Hi @Miraboreasau

ParaView indeed rely on naming to group file series together but clearly that doesnt work with your naming scheme.

Could you explain what you would like ?
