Immersed boundary method in OpenFoam
 

This would be a question for the Foam developing team: I am wondering if they'll incorporate immersed boundary method (based on interpolation) into its future new release as a module to handle the dynamic mesh if they are not doing so. They seem to have this idea. I am strongly interested in this because I am working on immersed boundary method myself for PhD. If they are doing so I'd like to know what stage they are in now.

Or anybody can give some information? Thanks:)

Have you already read this?

I think that Željko Tukovíc is working on it.

Thanks~
not sure how far he has gone. should I expect for this in the next release 1.7 ...;)

As far as I know if the code is going to be released or is now available, you must look into the extension project (i.e. OF-1.5-dev). That work has not been done in the dark side.

I have never seen a piece of code in there so far.

Hello,

does anybody know, if Immersed boundary method can be used right now?
the status on http://www.extend-project.de/
in development:
immersed boundary method (Uni Zagreb)
But
http://www.sfbtrr75.de/website/index...mid=30&lang=de
Dr. Tuković
- Immersed boundary method with RBF (Radial Basis Function) interpolation in Open FOAM
can somebody point me where to look for Immersed boundary method in extend?

thx

I second this.

IBM would be a great (and much needed) contribution to the OF community. It will make OF much competitive (comparing to, say, Flow3D).

Hi,
I am now trying to utilize the immersed boundary method implemented by Hrvoje Jasak and Željko Tukovíc. But I got some trouble in the case of parallelization. Anyone has the same trouble as me? I tried to dig a little and find some problems in the data transfer between processors in the implementation. But I cannot find out what it exactly is.

Best regards,

I am using this implementation right now and I have the same problem in parallelization as well. Did you manage to solve the problem?

It would be great if users can share their problems and experience around this topic here. But seems that there are only a few people interested in this topic.

Hi JinBiso,
I have the same problem. Have you solved this problem?

Hi, Hua,

I think the parallelization problem is brought by collecting data from different processors, because in parallelization case, each processor can only access data in its own subdomain. You can try to add sumOp to the source code, this can help you combine the data collected by all the processors.

Best wishes,
