[gmx-users] reciprocal vector of Ewald summation

[Zhenyu Meng]

Dear gmx users,
I'm curious about how to determine the magnitude of reciprocal vectors in
normal Ewald summation.
Take the example in the manual(4.6.5), the box length is 3nm and Fourier
spacing is 0.6, then it says there will be 11 wave vectors in each
direction.
How to get this value?
