Variation of periodic boundary condition

Hi folks, Greetings! I am trying to implement a variation of the periodic boundary condition in Transport of Diluted Species. The problem I am interested in involve a repeated geometry. Let's say a...

Re: Variation of periodic boundary condition

You have two unknowns: f_right and f_left, but only one equation relating them. Imagine a container with three holes, one inlet, two outlets. The outflow at the two outlets must together be the same as...

Re: Variation of periodic boundary condition

Hi Pieter, Thank you for your reply. I understand what you are saying. What I was thinking was that the left and right boundaries could be considered as periodic boundaries. I only have one inflow and...

Re: Variation of periodic boundary condition

So what you can do is specify the influx at the top and the left, and set an influx boundary condition at the right of -f-f_left. Right?

Re: Variation of periodic boundary condition

Yes, something like that. I will have to make assumption that flux along the right boundary is uniform though, since conservation of mass only tells the summation over boundaries is 0. I will have to...
