how to implement periodic boundary conditions?
Hi
I would like to implement periodic boundary conditions to model open channel flow in an existing code which only has inflow and outflow BC. It's a finite volume code with a staggered grid. Time discretisation is by forward Euler. Solution through a Poisson eq for the pressure. How should I deal with this? Katrien

I am using the periodic TDMA developed by Prof. Patankar. If you want to test it, please post here. I will give you that subroutine.
Good luck,

I have the same problem.Halim, can you send me the corresponding code, thanks

Re: how to implement periodic boundary conditions?
yes halim, I'm interested. thanks in advance!

Re: how to implement periodic boundary conditions?
Hi, Halim, would you please also send me a copy of the code for periodic TDMA? Thanks a lot.

Re: how to implement periodic boundary conditions?
Hi Halim, I am also having similar problem. Can you please provide the TDMA solver by Patankar to me also?

Re: how to implement periodic boundary conditions?
not the TDMA solver but Cylic TDMA solver.
