The volume for stress calculation

Dear All,
I’m wondering the volume used for pressure control is the total volume of atoms or the volume of the box?
Thanks.

two things:

- a please practice mailing list etiquette and don't copy a massive
mail that has nothing to do with your question. if you want people to
make an effort to help you, please have the courtesy and delete what
is not related to your mail or better yet write a new message from
scratch. how much more effort is it to cut-n-paste an e-mail address?

- what is the volume of a point particle?

axel.

How do you compute stresses from a pressure tensor. You always perform mathematical operations using the “”“Lengths of the domain”"". So its the volume of the box that you are looking for.
