All:

I recently finished my PhD involving FSI and thought some of you might be interested because I used OpenFOAM for my flow solver. I used my own structural finite element solver and built it with OpenFOAM to create a single executable (interface information is exchanged in RAM via an interface object). The FSI simulations were quasi-steady so I started with simpleFoam and made simpleFsiFoam. I have validated the solver with experimental results from water tunnel tests. The FSI solver is easily extended to unsteady simulations (which I have done) but I have not yet completed the solver validation.

If you are interested in more information, please refer to my thesis: http://www.personal.psu.edu/rlc138/r...ell_thesis.pdf. In it you will find how I communicate information for the disparate mesh interface, perform mesh motion, and tightly couple the solvers. The FSI solver also supports parallel solutions of the flow domain (which is the most time-consuming part - also described in my thesis).

Congrats, Rob!

Very good job, I am very interested, and will read it these days. Could you drop me a line (lakeat@gmail.com).. Thanks

wow! i'm interested in doing sth similiar in my phd thesis! this will certainly come in handy

Rob, I took the liberty to put a link on the wiki as well: http://openfoamwiki.net/index.php/Ma...Papers#Reports

Hello,

I ran a serial case of FSI in OF-1.5-dev version and it worked well, now i'm trying to run the same case in parallel but I get the error that is attached to this thread.
I read in other threads that mpi is integrated in OF-1.5-dev, so if this is the case there could be something wrong with OF compilation.

Any idea or help is greatly appreciated.

Regards,
Marzbali

Is currently this released code able to perform the parallel simulation? I thought it still just had the serial version released, one has to write the parallel code themselves.

[marzbali]

I ran one parallel case with interFoam in OF-1.5-dev and it worked, the thing is that I can't run FSI solver in parallel.

[lakeat]

I'm working on rigid body movement, and the parallel version solver works very well. But I don;t use the obsoleted *FSIFoam.

[marzbali]

I'm running myInterFsiFoam, which solver do you use?

[mechy]

I am interesting in FSI problems
can you explain to me what is the advantage of your solver with respect to icoFsiFoam that exist in OF-ext1.6 ?


best regards

[marzbali]

Hi,

not that it has more advantages, it is only because they are for different applications you know.

[Mojtaba.a]

Dear all,
Its a while I am searching for turbulent version of icoFsiFoam. obviousley it would be named simpleFsiFoam.

Is there anybody here developed such a solver which can share with us?

I greatly appreciate this.
Thank You,
Mojtaba

[RLFerreira]

Dear All, I am searching about solver for transient turbulent flow, including structure-fluid interaction. I have used icoFsiElasticNonLinULSolidFoam, however it solves transient laminar flow. Like Mojtaba asked previosly, Is there anybody here know about development of FSI solver for turbulent flow?

I will be very grateful for an answer. Best regards,
Ricardo Ferreira.

[rasool_soofi]

Hi Ricardo
You can use fsifoam solver.
but i want to know how did you validate icoFsiElasticNonLinULSolidFoam ? Because i cant validate icoFsiElasticNonLinULSolidFoam with default tutorial ( HronTurekFsi tutorial )
rasool

[RLFerreira]

Hi Rasool. Do you mean icoFsiFoam? I tried icoFsiFoam, but it is also for just laminar flow. I am validating icoFsiElasticNonLinULSolidFoam with some experimental results for Re=3,000 on flow acting on compressor valve.
Thanks for you answer! Best regards,
Ricardo.

[rasool_soofi]

Hi Ricardo
no. fsifoam solver that you can download from this link
https://openfoamwiki.net/index.php/E...re_interaction

[rasool_soofi]

Do you publish your validation or not ?
can i see that ?
because when i ran tutorial of icofsinonlinulelasticfoam ( hronturekfsi tutorial )in foam extend3.1 , the deformation of plate is not logical rather than results of hronturek benchmark problem ( that published in featflow website ( featflow.de website ).
can you help me ?
best regards
Rasool

[RLFerreira]

Hi Rasool. I am not publish my investigation, because my numerical model is not working very well yet. I think in next week I have model work and I will send you to see. Tkank you very much for Extended-Baazar FSI toolkits. I am fitting my model using it, because it is more complete. As soon as possible I'll write to you.

About hronturekfsi tutorial I just started to simulate to see solid motion, so I did not do detailed analysis of results. So, I can not conclude anything about that validade.

Best Regards,
Ricardo.

[rasool_soofi]

Hi Ricardo
thank you very much.
I am waiting for your response.
Best Regards.
Rasool.

Hi all,
Have you seen this:

https://github.com/unicfdlab/Trainin...pleFsi-OF3.0.0

It will be presented in 11th OpenFOAM workshop, Guimarães, Portugal:
http://www.openfoamworkshop.org/courses

Hope it helps.
