Hello

I am sorry if it is obvious but is there way to tell where the code style checks fails on the files? Looking at the the details section , only thing I can understand is that it failed to trim some trailing white spaces.

If you install the precommit hook it will take care of formatting for you https://su2code.github.io/docs_v7/Style-Guide/

@BerkeCan97 can you run pre-commit on the files? We can then continue merging this.
