Hi Syavash,

I am pretty sure that you have to define two surfaces when using cyclic BCs.

Of course it is not enough to define one patch without using cyclic patches. Thats the problem I...

Hi Syavash,

thats right, a cyclic channel flow is much more stable than a cyclic flat plate boundary flow, but it's absolutely not impossible to stabilize it!

About the averaging Time T, that...

Hey syavash,

Do you want to simulate transition in your channel flow? Or why isn't your inflow fully developed? I think that I don't understand your setup at all :mad:

When using Lunds BC, you...

Dear syavash,

the scaledMappedVelocity BC is based on the mappedBC to set values from one plane to another.

When you have a look at the mappedBC, you can see, that there are different...

It figured out that I have been pleased too early. When I run Joachims uploaded test case with scaledMappedVelocityFixedValueDelta (averagingTime=100), all seems to work fine. I can't reproduce his...

When I run Lunds BC with OpenFOAM-2.2.2, my parallel running problem is solved. This is weird, because Lunds BC should also work with OpenFOAM-2.2.0. So maybe I had an installation problem.

Thanks...

In the hope that this is my last question in this thread ...

To test Lunds BC I created a very simple mesh with blockMesh. Its dimensions are from (0 0 0) to (0.28288 0.09 0.0942592) in [m].

PS on Monday:
Your hint was perfect, OpenFOAM detects my BC without any problems. Now there seems to be another problem with a segmentation fault, but I'll try to solve it on my own before...

Hello FOAMers,

I'm also interested in Joachim's implementation of Lund's BC in OpenFOAM. Is it still possible to get the code from anybody who used it? I want to do some DNS with it and it would...
