Dear Developers and Users,
Is it possible to apply npt in only x and y directions but not in z-direction?

I was thinking if I will change the compressibility to zero, will it
solve the purpose?

That is exactly how you accomplish what you’re trying to do.

Thank you very much Prof. J. Lemkul for your response, I am already
implementing it.

Yes, it is. It depends on your system. You can control it using isotropic, semi-isotropic and an-isotropic conditions.
