FSI solver
 
Hi dear foamers
im going to simulate a non-Newtonian flow with flexible pipe.
it would be a fluid solid interaction (FSI)
which solver is suitable?
any hint or guideline ?

Maybe fsiFoam of OpenFOAM 1.6-extend?

I agree with Berhard http://openfoam-extend.git.sourcefor...alysis;hb=HEAD

http://powerlab.fsb.hr/ped/kturbo/Op...Zagreb2007.pdf
outdated (OF1.2) FSI presentation & newtonian only (just for completeness).
http://www.openfoamworkshop.org/08/p...V_Kanyanta.pdf

a good read is 6th OF workshop =>Block-coupled solvers, I. Clifford, PSU
=>Multi-Zonal Multi-Physics Modeling: FSI and Congjugate Heat/Mass Transfer,R. Campbell and B. Craven, PSU
Fluid-Structure Interaction on sail fabric type structures Daniele Trimarchi (University of Southampton)

Numerical simulation of sailing boats dynamics FSI and shape optimization Manifolds Matteo Lombardi (École Polytechnique Fédérale de Lausanne)

there will be more FSI stuff on the 7th OF workshop so watch that presentations in a couple of weeks when they are online

Hi again
i installed OpenFOAM 1.6-ext through debain pack,
in debain pack there is no example for icoFsiFoam.
and i could not launch to git "it gave me time out error connection"
However could you please put the solver example here

Hello,

how is your .bashrc for your debian installation of OpenFOAM 1.6-ext looking like?
My first impression is that this might be the cause of your trouble.

source /usr/lib/OpenFOAM-1.6-ext/etc/bashrc
export FOAM_TUTORIALS=/usr/share/doc/openfoam-1.6-ext/examples
... etc. This debian installation follows the debian guidelines and differs to OF habits

nimasam June 18, 2012 16:23

:) thanks for your reply, i found the example files in usr/share/doc but it dose not have any example for icoFsiFoam

Hi,

the tutorial case is http://openfoam-extend.git.sourcefor...eSmall;hb=HEAD

the solver is http://openfoam-extend.git.sourcefor...siFoam;hb=HEAD

or short cut sol cd stressAnalysis/icoFsiFoam to the sources.

I looked into 5th OF workshop installation and path there was
/usr/share/doc/openfoam-1.6-ext-dbg/examples/stressAnalysis/icoFsiFoam/flappingConsoleSmall to the "tutorial case example" consisting solid and fluid in seperate directories

hope that helps

as i said before, i found icoFsiFoam, but it does not have any example or tutorial case with it self: not in debain pack installation (http://openfoamwiki.net/index.php/Installation) not in kubuntu.iso from workshop (http://sourceforge.net/projects/openfoam-extend/)
and
i can not get OpenFOAM-extended from git with following command:
Quote:

git clone git://openfoam-extend.git.sourceforge.net/gitroot/openfoam-extend/OpenFOAM®-1.6-ext
because i face the following error:
Quote:

openfoam-extend.git.sourceforge.net[0: 216.34.181.91]: errno=Connection timed out
fatal: unable to connect a socket (Connection timed out)
however, thats why i asked, please put the test case here ;)

Greetings to all!

@Nima: check the front-page of the Extend-Project: http://www.extend-project.de/ - you'll find that the correct git clone command is this:
Code:

git clone git://openfoam-extend.git.sourceforge.net/gitroot/openfoam-extend/openfoam-extend OpenFOAM-1.6-ext
Best regards,
Bruno

nimasam June 23, 2012 15:17

same error even with your command

wyldckat June 23, 2012 15:42

Hi Nima,

Then try these, where the second should work even behind a firewall:
Code:

git clone git://repo.or.cz/OpenFOAM-1.6-ext.git
git clone http://repo.or.cz/r/OpenFOAM-1.6-ext.git

FYI: these are mirrors of the main Extend-Project repository.

Best regards,
Bruno
