You would have to code to implement a varying pressure of any sort, but
please think about what kind of physics your are trying to model first.
Is it all possible to have Ghz or even Thz pressure "waves"? If they are
much slower you have to simulate not ns or ps but much longer.
Is the pressure coming from air or from a (glass) wall? This may affect
what you want to implement.
Finally what measurements on proteins (just one?) will you be comparing
to? This should also influence your design decisions.
