Hello,  
I am using Paraview 5.11.2 with Linux Ubuntu 22. I have 64 Go of RAM on my computer.  
I am trying to make time steps animation with large vtk dataset 790 MB each, the group is composed of more than 100 files.  
Unfortunately, it seems to be too heavy for my computer, and at the bottom right and on the memory inspector, I can see only : “System total 5.07 Gio” and Paraview 1.04 GiB.  
I wonder if and how I can make Paraview to use more RAM ?

Thank you for your help,

Regards,  
Nina

This is not coherent, what is the output of ` free -h` ?
