I've executed the top command and i'm reporting the output.
As you can see Memory does never exceed 6.5%, i've already tried running the
simulation after having allocated more memory (namely 2.5 GB) to the wsl
system but the resulti s the same. By following the output log it seems the
simulation reaches this problem at time 112.000
The odd thing is that the simulation was running fine on microsoft 11. Due
to performance issues though i decided to roll back to the windows 10

SEGFAULTs can often mean you are running out of memory.
Though the tov_ET parfile uses very little memory for me: 200MiB (but does
reserve quite a bit more memory as virtual memory, namely ~1GiB).
You may need to run "top" in a second bash window to see how much memory
your run is using (you can type "e" to change units to more useful ones).
If you are actually running out of memory (which I kind of doubt, but who
knows) then you can try increasing memory for WSL2.
Since wsl2 is a (thin) virtual machine it is limited by how much memory it
Can you try if reserving more memory for the VM helps?
for how to do that.
I also noticed that the speed is a bit slower than expected with only
~71M/hr while my (old) workstation reaches ~1700M/hr.
For me the TOV
