Reply To: Periodic bc

Hi Mathias,
Thanks for the lead.I understand that the setPeriodicity() function in the cuboidGeometry class sets the periodicity.
Actually, I was looking for a stream-wise periodic boundary condition for channel/pipe flow with pressure gradient. One can achieve this with body force, but I read here that it is only applicable if the cross-section area is constant. Periodic bc with pressure gradient might include modification of the inlet density[Kim 2007]. I was wondering if this is already implemented in OpenLB?

Thanks!!
Best,
Nipin
