Hello everyone, are there any news regarding synthetic turbulence generation as an official pyfr feature and that works with v1.15? or with a new version of PyFR? Best regards, Amir ---

This feature is now merged into the develop branch on git. We are working on finalising the new features before making a new PyFR release, but the develop branch is stable and you can use that. ---

Thanks Will. I’ve modified all the ‘Turbulent inflow plugin’ files from github, but the following massage is occur after typing a commend: ```python Traceback (most recent call last): File "/home/anaconda3/envs/pyfr-venv/bin/pyfr", line 5, in from pyfr. __main__ import main File "/home/anaconda3/envs/pyfr-venv/lib/python3.9/site-packages/pyfr/ __main__.py", line 20, in from pyfr.solvers import get_solver File "/home/anaconda3/envs/pyfr-venv/lib/python3.9/site-packages/pyfr/solvers/ __init__.py", line 3, in from pyfr.integrators import get_integrator File "/home/anaconda3/envs/pyfr-venv/lib/python3.9/site-packages/pyfr/integrators/ __init__.py", line 5, in from pyfr.integrators.dual.phys import BaseDualController, BaseDualStepper File "/home/anaconda3/envs/pyfr-venv/lib/python3.9/site-packages/pyfr/integrators/dual/phys/ __init__.py", line 3, in from pyfr.integrators.dual.phys.controllers import BaseDualController File "/home/anaconda3/envs/pyfr-venv/lib/python3.9/site-packages/pyfr/integrators/dual/phys/controllers.py", line 3, in from pyfr.integrators.dual.phys.base import BaseDualIntegrator File "/home/anaconda3/envs/pyfr-venv/lib/python3.9/site-packages/pyfr/integrators/dual/phys/base.py", line 5, in from pyfr.integrators.base import BaseIntegrator File "/home/anaconda3/envs/pyfr-venv/lib/python3.9/site-packages/pyfr/integrators/base.py", line 13, in from pyfr.plugins import get_plugin File "/home/anaconda3/envs/pyfr-venv/lib/python3.9/site-packages/pyfr/plugins/ __init__.py", line 1, in from pyfr.plugins.ascent import AscentPlugin File "/home/anaconda3/envs/pyfr-venv/lib/python3.9/site-packages/pyfr/plugins/ascent.py", line 71 match value: ^ SyntaxError: invalid syntax ``` ---

The current develop version of PyFR requires Python 3.10 or newer. Regards, Freddie. ---

Please switch to develop version of PyFR proper. The plugin depends on a lot of extra functionality that was added to the core codebase since 1.15. Regards, Freddie. ---
