Hello, everyone

I add the patch file in pyfr, and run “patch \< stg.diff”, but it appears errors. Is anyone experiencing the same issue?

I’m not quiet sure where your patch has come from, but maybe consider `git apply`: [Git - git-apply Documentation](https://git-scm.com/docs/git-apply)

The patch is from synthetic turbulence generation paper. I use git apply, it shows all .py files are not directory.

You will need to apply this to a specific version of pyfr, as things have changed since that paper and it won’t work.
