I was wondering whether anyone is a user of FIDAP / FlowLab and would like to know whether these are available as freeware. I am learning CFD on OpenFoam but would like to be versatile in Fluent since it is industry standard. I was also wondering whether any users have utilized Ansys Flotran for Fluid-Solid interactions.

Dear friend,
Why don't you use FSI solver which is available in OpenFOAM (dev versions)? I've used both FLUENT and OpenFOAM;undoubtedly, OpenFOAM is much more reliable than FLUENT; at least you can see what's going on!
I think "industry standard" feature of FLUENT is an infirmity for that in comparison with OpenFOAM. I'm not familiar with FSI solvers of these two softwares but I found many bugs in FLUENT in my major field which cannot be removed.

Bests,

Dear Amir,

Thanks for the suggestion. However, to my knowledge the large displacement aspect that is possible in ANSYS or ADINA was not previously implemented in OpenFOAM. This is particularly a concern for biological flow-structure interaction studies. I was wondering whether you might have tried to interface OpenFOAM with Code Aster.

Hi,

As I said, I'm not aware of the FSI details, but as it's an open source software, it would be possible to correct some aspects and I think it's going on as you can see different sessions in each workshop in this regard.
About linking these codes, I have to say that, it's certainly possible if you can provide your necessary libraries and can change the C++ main code in OF to use them. (even that the code Aster would be in other languages since the libraries are independent of the language!)

Bests,
