how can I zero stress on the atoms of CNT after a run?

Dear All

how can I make make NULL or delete the stress on all atoms after a run and have a structure without any stress for the next Run?
Is there any command for doing this?

You need to relax the structure to its potential energy minimum.
Whether you can reach that with a simple minimization or you need a
more elaborate protocol depends on the specifics of your system.
