RE: [ff3d-users] Periodic BCs

[Bharat Rangan]

To start with a simple case, I want to solve the Navier Stioes in a box.(
Something like flow through a rectangular channel) . I want to apply a
periodic BC on the left and right faces so that whatever leaves the left
face enters the right face and the otherway.

Please give me a rough sketch as to how to implement this.

Thanks
Bharat Rangan

Yes, this is the right place for such questions.

Well. ff3d used to implement periodic boundary conditions, but it was
coded in hard: it means that there was no interface in the language.

Implementing periodic boundary conditions is not a big task, adding the
language interface is not so easy. Please tell me what you really need,
what is the problem you want to solve ? I think it should be quite easy
to implement something that fits your needs.
