Number of k-vectors is not consistent between orthogonal and cubic boxes

[emarinri]

Expected behavior

For a simulation with electrostatic interactions, the number of k-vectors in by a cubic box whose box length is X should be the same as those required by an orthogonal box whose box lenghts are all the same and equal to X.

Current behavior

The number of k-vectors is not the same between cubic and orthogonal boxes of same dimensions for the same system.

Steps to reproduce

Steps to reproduce the behavior:

1. Use the same exact system with the same box dimensions and the same cutoff
2. Run 1 simulation where the box is defined as cubic
3. Run 1 simulation where the box is defined as orthogonal
4. Check the number of k-space vectors for the two simulations
