How to define Periodic boundaries on Y Directions?
I want to simulation a poiseuille on which the Y direction Periodic,so what can i do?
Thank you!

Hello,
To define periodic BCs you have to “toggle” the direction in the lattice object (true is for periodic and false for non periodic).
lattice.periodicity().toggle(0,true); (0 is for X, 1 for Y, 2 for Z).
To toggle all the directions you can also do :
lattice.periodicity().toggleAll(true);
By default all the directions are “false”.
I hope it helps.
