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).

Rob

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

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.

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.

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

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

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

Hi,

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

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
