Synthetic turbulence

General

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:

The current develop version of PyFR requires Python 3.10 or newer.

Hello Freddie,

After performing all the required modifications, I keep getting the following error (I also tried different meshes but I’m getting the same error):

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.
