Hello, I am trying to follow the tutorials through the provided examples. So far, “2D Incompressible Cylinder Flow” example case working without issue. However, for the “3D Triangular Aerofoil” example case, I got the error below after command `pyfr -p run -b cuda triangular-aerofoil.pyfrm triangular-aerofoil.ini` Because I only have 1 GPU, I’ve also tried to run with 2 CPU cores after grid partitioning. “mpiexec -n 2 pyfr run -b openmp triangular-aerofoil.pyfrm triangular-aerofoil.ini” This also gave me error which is not exactly the same with the error from cuda command, but the last line of the error is the same “RuntimeError: Template “pyfr.plugins.kernels.turbulence” not found” Please let me know how I can fix this using either GPU or CPUs. Thank you! ```auto Traceback (most recent call last): File "/home/yongsu/Research/CFD/PyFR/libxsmm/pyfr-venv/bin/pyfr", line 8, in sys.exit(main()) ^^^^^^ File

I believe this is now fixed in the latest develop branch as of 2 days ago.
