Hi Hrv,

I have chosen a second option:
Extending the cylindrical sliding interface in vertical directions – this works very good (no errors, nice distribution of parameters). However I showed only a simplified case. On the top of my mixer i have something that will not "like" moving mesh topology so this solution is not suitable for me.

I concentrated on one sliding interface out of both sliders. This is something i am working on now and it is causing problems indeed.

Now I am diving in the code to understand better what is happening. I have still several things to check. If i manage to make it work i will post a solution. it may take me however 2-3 weeks (from Tuesday i'm on holiday in hot country not in Rainchester ).

Thanks for suggestions.

Hehe, Rainchester: I know exactly what you mean.

To be honest with you, I need encouragement and/or company to get this finished and it's quite a hard job. I am trying to assemble a group of people who can either join in or contribute in other ways to get this work restarted. For all those out there who need sliding interfaces, complex topo changes and parallelism, now is the time to join in.

In any case, give me a shout when you come back to the real world and we can look for a way to take this further.

Have a good holiday,

Hrv

Dear FOAM community,

I'm having a terrible time producing anything with icoDyMFoam. I cannot even reproduce the example cases delivered in this forum (kupplung, mixer3D). Okay, mixer2D ran fine. I do need some help for I'm from the Fortran community and a newbie to OpenFOAM.

1.) Case Kupplung runs until Time = 0.00573, but not beyond no matter what I do. The dramatic dying moment is captured here:

Any help on this matter would be highly appreciated. I'm studying fairly complex pump simulations with our own code and I'd like to replicate some of our cases with OpenFOAM. If only I could get past these problems ...

Have a look through the forum: the last sourceforge release is riddled with bugs and you need a patched up version.

With the latest commit of the overlapGgi boundary condition in the OpenFOAM-1.6-ext git repository, this problem is now finally solved for me.

Thanks,
Oliver
