Dear LAMMPS experts,

When periodic boundaries are applied, how should the length in that dimension be interpreted? Is it considered infinite, or is there a specific way to calculate its effective length?

To provide context, I am working on calculating the moment of inertia for a 3D cantilever with dimensions L, h, and w along the x, y, and z axes, respectively. In this case, I have applied periodic boundary conditions along the z-axis.

Your insights would be greatly appreciated!

Best regards,

Bahman
