thank you.I figured out the subject.a little thing i should correct is that sides are constant and i want to move channels in the middle altogether between ports that are stationary.

yeah, it is not important what moves and not only that you have partial overlapping in your geometry.

In GGI one can do that, but I know there is some kind of a sliding interface method to do that in OF. Some people who do combustion work with that a lot. I think you can find some help in checking some 1.6-ext tutorials.

should i install OpenFOAM extended version to use GGI or it can be compiled on ordinary version?

[wiedangel]

if you want to use GGI you have to install the 1.6-ext version. Did you find any thing concerning sliding interfaces? I think there was a talk about it in the last OpenFoam workshop, but I am not sure. Here is the link:

Good luck with your simulation.

Hello everyone,

I don't know if it is a bug, but I figured out following problem:
in a case with stationary-rotating-stationary part with rotating mesh (pimpleDyMFoam) and coupled with cyclicAMI in the first time step the interpolation weights are wrong.
This leads to a complete wrong pressure field in the first time step.

You can download a simple test case with a rotating pipe between stationary parts.
