lattice constant of vapor argon

​Hello everyone,

I want to simulate condensation of vapor argon in a nanochannel. I need lattice constant for vapor argon in the FCC style.
How can i calculate this lattice constant by having number of atoms and dimensions of simulation box?

regards

​only crystalline solids have their atoms on fixed lattice positions. what
you are asking for makes no sense.

dimensions of simulation box?

​why don't you just insert your argon atoms in random locations?​
