Hi Everyone,

I am simulating a droplet and i am using the translational periodic boundary condition so that when the droplet moves to the right boundary at the end of the domain it will re-appear on the left side of the domain. The problem i am facing is that when the droplet moves to the lower right side boundary, it re-appear on the upper left side boundary. So basically it translational on both X- and Y- axis.

How can i make it translational only in the X-Axis.
Does anyway one know?

Thanks.

another note, I am using 2-D Fluent 6.3 ..

Do you use Gambit for meshing? Then, first you have to "link mesh" on your bound-faces with option "Reversed orientation" checked. To Link faces (Gambit): Mesh->Faces->Link/Unlink faces.
Try to create conformal periodic zone as provided in guide.
Maybe, it'll help you.
N.B.: I'm not a big spec. in periodic b.c. in Fluent, I've studied it since today

Hi,
How can we use same periodic conditions to
1.flow with a pressure drop,which is geometrically periodic in nature,and is not fully developed
and also to
2.Flow with a pressure drop,and fully developed flow(like fully developed flow through circular pipe)
Iam getting confused.Any body please clarify.
