Hello,

I am wondering, if it is possible to exclude periodic interactions on negative faces of periodic cell (those with outer normal against coordinate axes) while preserving periodic contacts on positive faces.

Dividing the cell into 3 parts in each directions and using bitmasks could be one solution, but I would like not to use this one. I want to use it in a very special case where I use a lot of masks for a lot of periodic cells using actually one periodic cell. So, introducing 6 bits for each one, I would run out of int width.

Thanks
Jan
