Krylov solver's option max_it and a few questions

As I do not have arch, I cannot reproduce the error. Could you try with the binary from: Download ParaView
?

I am actually trying hard… I downloaded the Linux version “ParaView-5.12.0-RC1-MPI-Linux-Python3.10-x86_64/”, I have a permission error to execute the binary despite a chmod +x on paraview’s binary.
“source ./paraview” within a bash session leads to bash: source: ./paraview: cannot execute binary file as if it wasn’t compiled for my architecture. But I am using Linux on a x86_64 machine…

So what happens if you simply do ~/path/to/ParaView-5.12.0-RC1-MPI-Linux-Python3.10-x86_64/bin/paraview in the terminal?

On my system:

 ~/Downloads/ParaView-5.11.2-MPI-Linux-Python3.9-x86_64/bin/paraview 

works nicely

I get:
error: process error: Permission denied

Not sure if this helps. But ls -l yields:

chmod +x all the other binaries “work”. I can load my temperature.bp file. I can see the solution with colors, just like I used to do with xdmf files.
So this mean Arch Linux’s paraview is bugged?
