FSI
 

I am wanting to run an FSI simulation using a commercial CFD hopefully CFX, maybe fluent to an in house structural code. I can export my pressure from the cfd and import to the structural but am struggling to get my new geometry back into my cfd code and then re-mesh?

Any ideas how I could go about this? Would adaptive or dynamic meshing do the job? Do I have to restart the simulation at each new time step with a new geometry?

Re: FSI
 

As I know, CFX can do that witout any problem. What you mean is the definition of a interface procedure for data interpolation beetween CFD and structural model. If you want to do that in FLUENT maybe you can look on the net for MPCCI. If you want to create your own procedure I'd suggest downloading my paper at http://www.aero.polimi.it/~quaranta/publi.html

presented at IFASD 2005. Hope it helps Luca

I think MPCCI will be too expensive for my research, an ideas of any alternatives out there?

Unfortunately no more ideas. You should write your own procedure. In the article you find in my paper there are some references. Luca
