About restarting with a new ini file

Cases

Hello, everyone.
I would like to ask if it is possible to restart a calculation to use a new ini file?

For example, I was using 2nd order NS equations and restarted to use 3rd order NS equations.

Yes, see:

pyfr restart --help
usage: pyfr restart [-h] --backend {cuda,hip,metal,opencl,openmp} mesh soln [cfg]

positional arguments:
  mesh                  mesh file
  soln                  solution file
  cfg                   new config file

options:
  -h, --help            show this help message and exit
  --backend {cuda,hip,metal,opencl,openmp}, -b {cuda,hip,metal,opencl,openmp}
                        backend to use

where you will see a third optional argument [cfg] whose description is new config file.
