Stress and flow analysis together
Greetings everyone,
I'm using OpenFoam for couple of weeks now, and I'm working on a particular case.
Here is my geometry :
I would like to have an obstacle who can bent a bit, so to add a soft material.
But it seems this case is a stress analysis and a classical flow analysis. Is it possible to make both at the same time? Do you know a tutorial or a website that could help me a bit in my work?

Thanks a lot in advance

Hi Antoine,

I think you are looking for a Fluid-Structure-Interaction solver, have you tried icoFsiFoam?
It is in $FOAM_SOLVERS/stressAnalysis/icoFsiFoam in OpenFoam-1.6-ext.
I am not sure if there is a tutorial for it.

Thank you very much indeed for your help Philip. FSI solver is what I'm looking for.
Do you think icoStrucFoam works well with my case ?
I can't find icoFsiFoam on the OpenFoam-1.7 version.

icoFsiFoam is only available in OpenFOAM extend (OF-1.6-ext, OF-1.5-dev, etc.).

I do not know know too much about FSI in OpenFOAM but there should be quite a bit of information on it, even if you search "fluid structure interaction openfoam" on google.
