Hi Zhang,
Thanks for your interest in PyFR. If you run pyfr-sim -h you will get:
usage: pyfr-sim [-h] [--verbose] [--backend BACKEND] [--progress]
[--nansweep N]
{run,restart} ...
Runs a PyFR simulation
positional arguments:
{run,restart} sub-command help
run run --help
restart restart --help
optional arguments:
-h, --help show this help message and exit
--verbose, -v
--backend BACKEND, -b BACKEND
Backend to use
--progress, -p show a progress bar
--nansweep N, -n N check for NaNs every N steps
Note the -b option to choose the backend you want to run with.
The default is -b cuda which will run the CUDA backend and look for an Nvidia
GPU. If you want to use your CPU you can use the -b openmp backend, and if you
want to use your AMD GPU you will need to use the -b opencl backend. However
note the dependencies listed here http://www.pyfr.org/user_guide.php for each
backend.
Cheers
Peter

Dear Prof. Vincent:
can I turn of cuda and make comparison for pure cpu and by cuda accelerations?
because I noticed even if when I don't have have backend-cuda, still the solver
will run on graphic card.
cheers

Dear Pyfrer:
I am very new to pyfr. I want to know does pyfr support quasi 2D simulation
with one direction by spectrum method?
cheers
