Thanks leflix for the attachment. But I think Patankar solved the same problem and reported his work in:

Thanks for your suggestions. suggestion (i) makes sense and I'm gonna apply it know. About your second suggestion, your right; I am applying Dirichlet BC which is kinda explicit. But how can I apply...

There is something with your comment that doesn't make sense to me. I am working with a collocated grid (not a staggered one). In my new geometry, my...

From your underlined comment, you might probably mean to consider a reference pressure. If so, I do consider a point, but adjacent to my inlet at (2,2), and subtract its pressure correction (from...

Maybe I am wrong and as leflix mentioned, I need to consider it as cyclic. The reason I consider it as periodic (or cyclic) is that the flow is repeating. I don't want to model 10 blocks because of...

The single cube problem is not periodic but I want to model a chain of cubes in a line so that any cube (or block) is in the flow downstream of the previous block (and not in fully developed flow)....

I am pretty confused. As long as I am model a square (2D cube) in a duct flow, I have no problem and the solution converges. For this case I have velocity inlet and outflow boundary conditions....

Implementation of Periodic Boundary Condition

Hi all,

I am going to implement periodic boundary condition in my own code. FYI, I am modeling a 2D duct with two wall mounted objects at top and bottom walls with a code that works with both...
