Hi @gibertini. I just saw this pull request. I assume that the code has been fixed?

[gibertini]

@trumanmiguel : yes, the code should be fixed now. Let's wait for the pull request to be accepted.

Thanks Marco @gibertini !

[giovannipizzi]

@trumanmiguel this is now merged in the main code. Could you please check if this works as expected or still has issues? Thanks!

[trumanmiguel]

Hi @giovannipizzi. The code works fine when I used it in my calculation. Thanks.

@giovannipizzi @gibertini:

I think @djitech13 and I just ran into the same issue. Current blame in the develop branch shows that the changes might have been reverted. Maybe I'm wrong though!
